2 Timothy 1:12-13

This is why I suffer as I do. Still, I am not ashamed; for I know Him [and I am personally acquainted with Him] whom I have believed [with absolute trust and confidence in Him and in the truth of His deity], and I am persuaded [beyond any doubt] that He is able to guard that which I have entrusted to Him until that day [when I stand before Him]. [1 Cor 1:8, 3:13; Phil 1:6] Keep and follow the pattern of sound teaching (doctrine) which you have heard from me, in the faith and love which are in Christ Jesus.
