God’s plan of salvation is not innate knowledge. It must be revealed to us. We could never come up with a plan as intricate and loving as God’s plan for his Son and for all of us. That knowledge must be revealed to us by the Holy Spirit. He is the one who creates faith in our hearts and shows us that we were created and designed for a purpose, that we are loved and forgiven through Christ. And it is our job to tell others the good news so the Holy Spirit can work in their hearts as well.
