In my estimation, for what it is worth, it is very important that we obey, for it is the Holy Mark of one who possesses True Salvation. The below text shows that a Child of God [will] become more like Christ, and the point of that statement means Obedience.
2 Corinthians 3:14-18 KJV - "But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. But even unto this day, when Moses is read, the vail is upon their heart. Nevertheless when it shall turn to the Lord, the vail shall be taken away. Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty. But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord."
Now, either these Scriptures are True or they are a lie. I hope we agree that they are to be read as True and accurate. So, if they are True, then a True Child of God [will] become more and more like Christ . . . one who actually walks the walk.
Unfortunately, for those who have not found that their sense of obedience shows an average of an incline, there is a serious problem. And if this problem exists, then we need to test the Spirit within ourselves. We are either led and guided by the Devil, or we are Led and Guided by the Holy Spirit if indeed the Holy Spirit is within us. See below:
Romans 8:9 NLT - "But you are not controlled by your sinful nature. You are controlled by the Spirit if you have the Spirit of God living in you. (And remember that those who do not have the Spirit of Christ living in them do not belong to him at all.)"
So you can see . . . we are either being led into Holy Obedience, or we are being led into sin by our True Father, the Devil.
But hey, I could be wrong about these Scriptures and getting it all wrong.
