"Add to your faith virtue" 2 Peter 1:5
"Furnish your faith with resolution." Moffatt
"'Add' means there is something we have to do. We are in danger of forgetting that we cannot do what God does, and that God will not do what we can do. We cannot save ourselves nor sanctify ourselves, God does that; but God will not give us good habits, He will not give us character, He will not make us walk aright. We have to do all that ourselves, we have to work out the salvation God has worked in. 'Add' means to get into the habit of doing things, and in the initial stages it is difficult. To take the initiative is to make a beginning, to instruct yourself in the way you have to go."
