(2Ti 4:5) “But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.” To make “full proof of thy ministry” is to minister in such a way as to prove you are God’s man. Our conduct before both the lost and the saved is to be such, that one can see the effect of the new birth in us. We have been made different from the world and should live like it. Why would those who have been freed from the power of sin wish to live like the lost? Live so others may know you are God’s sons and daughters!
