If you haven't learned about the Bible doctrine of "irresistible grace", then your denominational teacher, leader, priest or whoever taught you theology has obviously failed you.
It's quite sad to see shepherds hiding the truth of the gospel from their flock.
The first thing I would like to tech you is that the Bible doesn't spell everything out for you in elementary terms. Sometime you actually need to connect the dots to see the picture.
Here's a few verses to help you connect the dots.
John 6:44, which states no one can come to Jesus unless the Father draws them, and Ephesians 2:8-9, which says salvation is a gift of God, not by human will. Other key verses include Romans 8:30, which shows that God's calling leads to glorification, and Acts 16:14, where the Lord opens the heart of Lydia to listen to Paul.
Do you really believe that men are more powerful than God????, do you really believe that men can stop God from doing what He wants to do. News flash, that';s exactly what you’re suggesting here.
