Aspiring Man of God
There is a 53 part teaching series on Soteriology (the Doctrine of salvation) by Andy Woods on this forum, under “Sermons - Preachers pulpit” section. The below links are for the first 6. Very informative teachings.
I also highly recommend this series. It was a huge huge blessing to me when I watched it at a time the enemy was really tormenting me about my salvation.
