Philippians 2:12–13 “12 So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling;
13 for it is God who is at work in you, both to will and to work for His good pleasure.”
2 Peter 1:10 “10 Therefore, brethren, be all the more diligent to make certain about His calling and choosing you; for as long as you practice these things, you will never stumble;”
