God changes our character but not our personality, they are different things.
Personality refers to individual differences in characteristic patterns of thinking, feeling and behaving. The study of personality focuses on two broad areas: One is understanding individual differences in particular personality characteristics, such as sociability or irritability. The other is understanding how the various parts of a person come together as a whole. They are broken up into 4 groups.
The sanguine temperament is fundamentally impulsive and pleasure-seeking; sanguine people are sociable and charismatic. They tend to enjoy social gatherings, making new friends and tend to be boisterous. They are usually quite creative and often daydream. However, some alone time is crucial for those of this temperament. Sanguine can also mean sensitive, compassionate and thoughtful. Sanguine personalities generally struggle with following tasks all the way through, are chronically late, and tend to be forgetful and sometimes a little sarcastic. Often, when they pursue a new hobby, they lose interest as soon as it ceases to be engaging or fun. They are very much people persons. They are talkative and not shy. Sanguines generally have an almost shameless nature, certain that what they are doing is right. They have no lack of confidence.
The choleric temperament is fundamentally ambitious and leader-like. They have a lot of aggression, energy, and/or passion, and try to instill it in others. They can dominate people of other temperaments, especially phlegmatic types. Many great charismatic military and political figures were choleric. They like to be in charge of everything. However, cholerics also tend to be either highly disorganized or highly organized. They do not have in-between setups, only one extreme to another. As well as being leader-like and assertive, cholerics also fall into deep and sudden depression. Essentially, they are very much prone to mood swings.
The melancholic temperament is fundamentally introverted and thoughtful. Melancholic people often were perceived as very (or overly) pondering and considerate, getting rather worried when they could not be on time for events. Melancholics can be highly creative in activities such as poetry and art – and can become preoccupied with the tragedy and cruelty in the world. Often they are perfectionists. They are self-reliant and independent; one negative part of being a melancholic is that they can get so involved in what they are doing they forget to think of others.
The phlegmatic temperament is fundamentally relaxed and quiet, ranging from warmly attentive to lazily sluggish. Phlegmatics tend to be content with themselves and are kind. They are accepting and affectionate. They may be receptive and shy and often prefer stability to uncertainty and change. They are consistent, relaxed, calm, rational, curious, and observant, qualities that make them good administrators. They can also be passive-aggressive.
Character is an evaluation of a particular individual’s stable moral qualities. The concept of character can imply a variety of attributes including the existence or lack of virtues such as empathy, courage, fortitude, honesty, and loyalty, or of good behaviors or habits. Moral character primarily refers to the assemblage of qualities that distinguish one individual from another
Character is defined as strength of moral fiber. A.W. Tozer described character as “the excellence of moral beings.” As the excellence of gold is its purity and the excellence of art is its beauty, so the excellence of man is his character. Persons of character are noted for their honesty, ethics, and charity. Descriptions such as “man of principle” and “woman of integrity” are assertions of character. A lack of character is moral deficiency, and persons lacking character tend to behave dishonestly, unethically, and uncharitably.
A person’s character is the sum of his or her disposition, thoughts, intentions, desires, and actions. It is good to remember that character is gauged by general tendencies, not on the basis of a few isolated actions. We must look at the whole life. For example, King David was a man of good character (1 Samuel 13:14) although he sinned on occasion (2 Samuel 11). And although King Ahab may have acted nobly once (1 Kings 22:35), he was still a man of overall bad character (1 Kings 16:33). Several people in the Bible are described as having noble character: Ruth (Ruth 3:11), Hanani (Nehemiah 7:2), David (Psalm 78:72), and Job (Job 2:3). These individuals’ lives were distinguished by persistent moral virtue.
Character is influenced and developed by our choices. Daniel “resolved not to defile himself” in Babylon Daniel 1:8 But Daniel was determined not to defile himself by eating the food and wine given to them by the king. He asked the chief of staff for permission not to eat these unacceptable foods, and that Godly choice was an important step in formulating an unassailable integrity in the young man’s life. Character, in turn, influences our choices. “The integrity of the upright guides them” Proverbs 11:3Honesty guides good people; dishonesty destroys treacherous people. Character will help us weather the storms of life and keep us from sin Proverbs 10:9People with integrity walk safely,but those who follow crooked paths will be exposed.
It is the Lord’s purpose to develop character within us. Proverbs 17:3 Fire tests the purity of silver and gold, but the LORD tests the heart.
Baptism of Fire, Godly character is the result of the Holy Spirit’s work of sanctification. Sanctification, or in its verbal form, sanctify, literally means “to set apart” for special use or purpose, that is, to make holy or sacred. Therefore, sanctification refers to the state or process of being set apart, i.e. made holy.
Character in the believer is a consistent manifestation of Jesus in his life. It is the purity of heart that God gives becoming purity in action. God sometimes uses trials to strengthen character:
Romans 5:3-5 We can rejoice, too, when we run into problems and trials, for we know that they help us develop endurance. 4 And endurance develops strength of character, and character strengthens our confident hope of salvation. 5 And this hope will not lead to disappointment. For we know how dearly God loves us, because he has given us the Holy Spirit to fill our hearts with his love.
The Lord is pleased when His children grow in character. “You test the heart and are pleased with integrity” (1 Chronicles 29:17;
Psalms 15:1-2 (NLT)Who may worship in your sanctuary, Lord? Who may enter your presence on your holy hill?2 Those who lead blameless lives and do what is right,speaking the truth from sincere hearts.
We can develop character by controlling our thoughts (Philippians 4:8 (HCSB) 8 Finally brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable—if there is any moral excellence and if there is any praise—dwell on these things., practicing Christian virtues (2 Peter 1:5-6), guarding our hearts (Proverbs 4:23;Matthew 15:18-20), and keeping good company (1 Corinthians 15:33). Men and women of character will set a good example for others to follow, and their godly reputation will be evident to all (Titus 2:7-8).
It comes into being intimate with God through reading His word, praying, and worship. When you spend time with God he will increase in your life as you decrease John 3:30(HCSB) He must increase, but I must decrease.”, His will becomes your will.
Romans 6:6 (NLT)We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. 7 For one who has died has been set free from sin.
Galatians 5:24(NLT) And those who belong to Christ Jesus have crucified the flesh with its passions and desires.25 If we live by the Spirit, let us also keep in step with the Spirit.
Colossians 3:55 (NLT)Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry.
To have Godly character we must kill the flesh and feed the spirit.
Galatians 5:17 (NLT)The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other, so you are not free to carry out your good intentions.
