General Douglas MacArthur stated that in war there is no substitute for victory. The Christian is to put on the whole armor of God. That armor did not include any provision for the back. The Christian is not to retreat but to go forward. Jesus said He would build His church (Matthew 16) and the gates of hell would not prevail against it.
The Greek word for “prevail” means that the church is on the offensive, not the defensive. The church will go forward victoriously and the gates of hell will not be able to withstand that offensive.
