My thoughts below are inspired from Jeff Iorg’s book The Character of Leadership.
“The desire to become more like Jesus is evidence of a healthy Christian commitment. You are seeking God’s ultimate purpose and expect to be changed. For this process to genuinely result in Christ being formed in you, however, the Bible must be a vital part of your life. You must submit this entire process of character development to the Word of God and what it teaches about life, about God, and about experiencing God. ~Jeff Iorg
It is not the circumstance alone that causes us to form the character of Christ. It is choosing to deal with our circumstances in a Christ like behavior.
For example, how did Jesus treat those who opposed him? Did he retaliate? No. He did what he told us to do. He prayed for them (Matthew 5:44, Luke 23:34).
These are just few examples on how to build Christlike character. What are some other ways?
