We can be blocked by God based upon sin and the way out is repentance. We can also be blocked in based on the providence of God. The question to ask is what does God want from you? Once we know what God wants, then we must submit to what He wants! It sounds simple but it can be quite difficult.
Second once you’ve given what God asked from you, stand by faith on this side of the Red Sea knowing that God can and will deliver you!
