First, it means we all need correction. Second, correction only works if a deterrent is attached. Third, worldly deterrents are based on fear, loss, and pain. Fourth, godly deterrents are based on love, gain, and suffering. Fifth, worldly correction aims to punish. Sixth, godly correction aims to prosper.
There are still more differences between the two, but we get the idea.
For the Christian, regardless of the source of our correction, we should view it as from the Lord. Others may mean it for evil, but God always to our good.
I have always liked that Paul wrote that he was a prisoner of the Lord Jesus Christ. Roman soldiers placed him in prison. They did so at the behest of the religious leaders. But God wanted him there.
