1 John 5:19 GNT tells us, "We know that we belong to God even though the whole world is under the rule of the Evil One." We live in a world that is morally warped and spiritually perverted. That's why we need the indwelling of the Holy Spirit. That's why we need to learn to constantly yield to the Holy Spirit throughout the day.
Being born again is only the beginning of our salvation. God's purpose is to conform us to the image of His Son (Romans 8:29) and to transform us by the renewing of our mind (Romans 12:2). It is possible to have a "born again" heart but a "humanistic" mind. In fact, it is normal to think humanistically for we live in an unbelieving society and are indoctrinated by a godless and humanistic education system. The only way we can get our mind to catch up with our heart is to be renewed by the Word of God and the Spirit of God.
Do you think like God thinks? Or like society around you? Often we don't even know that we think like society because we are not filled with God's Word which exposes the deceptions.
What about our children? Are they being educated by our public education system? If so, they will be daily and subtly programmed to think oppositely to God's Word. It amazes me that believing parents are happy for their children's minds to be "renewed" in humanistic ideologies. Shouldn't it be our consuming passion for our children to be "renewed" in the ways of God so they will be confirmed to the image of Jesus? They will be "renewed" one way or the other.
What is our goal? To train children to be humanists? Or train children who will live according to Romans 12:2, "Be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
