The transformation Christ gives by the transfer of His life is real and effective in results. By conversion of God coming into one's life to take over one can truly experience a supernatural transformation that is sweeping and completely occurs. The salvation of born again experience occurs as God and the man or woman cooperate in not religion but relationship believing God is real and knowable personally. But for it to actually bring the results you want there has to be a change of mind and thinking so that by grace through faith one turns to God for help, admits they are wrong, before God and sinful in nature, (unable to please God in yourself,) then accept Christ inside as He Finished His Work of Atoning Sacrifice by His Death on the cross to become sin and specifically our yours and mine sin, and thus save us by His vicarious life, Death, burial, and Resurrection! In addition, va- oi-la you are saved in God's Sight having glimpsed His Kingdom and asked Him to forgive you and save you. You believe the Bible and from then on in the words of this Book they change you in your thinking and literally sanctify or change your heart to instead by daily reading the Bible and prayer, and fellowship with God, one on one, interacting converse with God the Person. God cleans up behavior but most of all gets to the root where the problem of man's nature lies. He gives a new heart, a new spirit, and a newness of life! II Cor 5:17. He takes the old heart out. He writes the law of God in the fleshy tables of your heart. He cleanses the conscience to serve the Living God. You become more of whom you are and were meant to be in light. It is more than insurance against hell fire but a new journey of eating at God’s Table where there is ways bounty! And Store! Inheritance! Peace! Come as you are. He takes care of the rest.
Is there a way to curb unscrupulous behavior in adults?
Legislation just does not do the trick, and (in my opinion) it's wrong to lock someone up for doing something immoral (that does not hurt anyone, at least.) It seems the only other option is education, but even then, it is hit or miss.
