Great Sermon! Dear Brother,
I thank God for your outstanding message from God. I've never heard such powerful Spirit-filled anointed preaching from a Presbyterian church in my life.
I thank the Lord for the vision He has given you. Keep preaching His eternal word.
I've come out of a PCUSA church as you well know that is an apostate church and I thank God from delivering me out of the depth of darkness, I worked there as a minister of music, I've never really believed much that was spouted from the pulpit, but it was the Lord's doing to grow me up in my walk with Him.
I know that there is a distinct difference between PCA and PCUSA and your distinction comes by being evangelical, Amen.
God is great in all of His ways. Be encouraged.
