The Book - The Man Who Loved The Truth.
To work something out involves time
The very same point is made in this next scripture: " For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God." ( 1 Co 1:18 )
The Apostle Peter, also, agrees with these words: Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation." ( 1 Pe 2:2 )
Growing is a time factor-the reward comes in time.
The Apostle Paul shows in this next passage that salvation is conditional: "Now brothers, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved if you hold firmly to the word I preached to you, otherwise you have believed in vain." ( 1 Co 15:1-2 )
