2 Peter 1:10

Therefore, believers, be all the more diligent to make certain about His calling and choosing you (be sure that your behavior reflects and confirms your relationship with God) for by doing these things (actively developing these virtues) you will never stumble (in your spiritual growth and will live a life that leads others away from sin).

Our faith and salvation in Jesus aren’t just to be believed but acted out. Just like an apple tree bears apples according to its kind, so should we, as Christian’s bear fruit according to Jesus. By acting according to the word of our faith, we develop our spirits and confidence in God.
