Why is being converted important for Christians?

Conversion is important for Christians as it signifies a complete change of heart and purpose. In Matthew 18:3, Jesus states that unless one becomes as little children, showing humility and willingness to be taught, they cannot enter the kingdom of heaven. Conversion is not merely an external makeover; it is an internal transformation where a sinner is made new in Christ. This shift allows believers to live in accordance with God's will and experience true fellowship with Him. It emphasizes the necessity of divine intervention to achieve true spiritual renewal.
