“Putting on the new self…” [Ephesians 4:23]
Anyone out there who has downloaded a new system—most especially windows 10 will understand [unless you are a geek] the awful frustration of getting rid of the old and understanding the new. Anything new will always destabilize an already existing and accepted system and the old program or system maybe gone from the computer, but working with the new is a learning curve in thinking differently.
This same principle holds true as Children of God, we must not be conformed to the ways of the world, but rather be renewed in our minds until we have a new system of thinking. It is also the reason man resists change of any kind and emphatically denies the need for Salvation, until the grace of God reaches for us. “You see, at just the right time, when we were still powerless, Christ died for the ungodly.” [Romans 5:8]
To understand this process Eugene Peterson uses this language “No one cuts up a fine silk scarf to patch old work clothes; you want fabrics that match. And you don’t put your wine in cracked bottles.” [Mathew 9:17- TM] Being born again by faith in Christ brings a complete transformation that is accomplished by obedience to the One who is the Creator of every creature. God has His own way and system of thought. “…so are my ways higher than your ways and my thoughts than your thoughts.” [Isaiah 55:9b]
The one who seeks to know truth shall be found by the truth—the truth has been established in all that we see and hear. They are the systems and principles of God, but it takes a hungry heart to see and accept them.
