Do what God ensured would be done

God is able guard it, therefore guard it:

“I am convinced that he is able to guard until that Day what has been entrusted to me… By the Holy Spirit who dwells within us, guard the good deposit entrusted to you.” (2 Timothy 1:12,14)

Work it out, because God it at work in you:

“Work out your own salvation with fear and trembling, for it is God who works in you.” (Philippians 2:12-13)

Make it your own, because Christ has made you his own:

“I press on to make it my own, because Christ Jesus has made me his own.” (Philippians 3:12)
