What does the Bible say about faith and love in Christians?

The character cultivated in believers is one of faith and love, reflecting the nature of Christ himself. As stated in Colossians 4, Paul's greetings emphasize the significance of faithful brethren, such as Tychicus and Onesimus, who exemplified these virtues. This transformation occurs when Christ dwells in the believer, creating a new man in the image of Christ, which is faithful, holy, and full of love. Thus, true faith and love are not mere human endeavors, but divine qualities forged by Christ within us.
