In the bible we find the Greek word homologeo which is a combination of two Greek words homou [at the same place, at the same time, having a close association (together or togetherness)] and logos[something said, something thought, communication, speech, frame, works].
So confession is saying the same thing God and His word are saying for a particular situation; thinking the same thing God and his word are thinking about a particular situation, having the same frame of mind that Christ has. Let this mind be in you which also was in Christ Jesus
(Philippians 2:5). It is doing the same work Jesus is doing. It is being at the same place where God instructed us to be. It is being one with God: what He says is what we say, what he does is what we do, where He goes is where we go.
As born again Christians our life is a life of confession, whether we have realized it or not we have been confessing. Let us apply that confession in specific areas.
