“LORD my God, I called to you for help, and you healed me.”
Ephesians 4:22-24 shows that major changes must occur when we are converted to serve God. Old practices and attitudes must be replaced by new ones. Christians must learn good habits like Bible study, prayer, love, faith, patience, attending church meetings, giving, teaching others, etc. We must also eliminate bad habits like foul language, uncontrolled temper, gambling, drugs, smoking, drinking, gossip, lying, pornography, sexual promiscuity, etc.
Knowing what changes to make is not enough. We also need to know how to make them. Change does not come easily. Since the Scriptures provide us to all good works (2 Timothy 3:16,17), they give all the guidance we need. God's word is the best source of guidance for self-help and motivation for self-improvement.
I believe in you and you need to believe in you too.
