Your character is essentially

Put on the new self, created to be like God in true righteousness and holiness. Ephesians 4:24 (NIV)

Your character is essentially the sum of your habits; it is how you habitually act. The Bible says, "Put on the new self, created to be like God in true righteousness and holiness" (Ephesians 4:24 NIV).

God uses his Word, people, and circumstances to mold us. All three are indispensable for character development. God's Word provides the truth we need to grow, God's people provide the support we need to grow, and circumstances provide the environment to practice Christlikeness.

If you study and apply God's Word, connect regularly with other believers, and learn to trust God in difficult circumstances, I guarantee you will become more like Jesus.
Many people assume all that is needed for spiritual growth is Bible study and prayer. But some issues in life will never be changed by Bible study or prayer alone. God uses people. He usually prefers to work through people rather than perform miracles, so that we will depend on each other for fellowship. He wants us to grow together.

In many religions, the people considered to be the most spiritually mature and holy are those who isolate themselves from others in mountaintop monasteries, uninfected by contact with other people.

But this is a gross misunderstanding. Spiritual maturity is not a solitary, individual pursuit!

You cannot grow to Christlikeness in isolation. You must be around other people and interact with them. You need to be a part of a church and community.
Why? Because true spiritual maturity is all about learning to love like Jesus, and you can't practice being like Jesus without being in relationship with other people.
Remember that during this Christmas season, when your family or friends challenge your ability to respond like Jesus!!

Remember, it's all about love - loving God and loving others.

In your life, you will be hurt by others; sometimes intentionally, sometimes unintentionally. How you handle that hurt determines your happiness.
