The Word says that His ways are higher than our ways. It states God is the Alpha and the Omega. He knows the beginning from the end. He is omniscient.

When we believe in Jesus and receive His Spirit with our confession of faith, our predestination Heaven is sure. God never predestinations people to hell. We did that ourselves.
