2 Timothy 1:12-14

For this reason I also suffer these things, but I am not ashamed; for I know whom I have believed and I am convinced that He is able to guard what I have entrusted to Him until that day. Retain the standard of sound words which you have heard from me, in the faith and love which are in Christ Jesus. Guard, through the Holy Spirit who dwells in us, the treasure which has been entrusted to you.
