If all the blessed old saints would remember that faith in Christ saves, not the law, then maybe they could stop offending people with their mouth.
Encourage the younger generation to pray and study the Word. Then teach them how.
Let the Holy Spirit take care of sanctification.
Romans 4
“being fully persuaded that God had power to do what he had promised. This is why it was credited to him as righteousness”
Romans 4:21-22
