Does God give different rewards in heaven? Does it matter what we do with His blessings on earth?
James 2:14-17 tells us that faith without works is dead. If we claim to know and love Jesus, then we must know and love people like Jesus did. If we claim to love God, we must love what God loves. Preach the gospel, heal the sick, make disciples, love your neighbor.... It's not easy, but this is a call to a new way of life that leads to rewards in heaven.
