Now, having said all that, let me be clear that I am not saying we can't use commentaries and books and articles and audio/video recordings. But there is no course, no method, other than to share the truth of God's Word and wait on the Holy Spirit to regenerate the elect and give them a new heart, so that they come to understand that their sin was imputed to Christ and Christ's righteousness was imputed to them.
I agree whole heartedly and since you were in the same area in post #12 Ken I would like to add this from his second... Brother Glen
2 Timothy 2:1 Thou therefore, my son, be strong in the grace that is in Christ Jesus.
2:2 And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.
