If someone REALLY believes in God’s Son, including what’s said in John 3:16-18, then they will understand and care that God HATES sin. Jesus suffered what He did because God hates sin. If we APPRECIATE what God and His Son did for us, then we will want to do God’s will for us.
The Bible says God created us to do GOOD WORKS and He set up those good works for us to do in advance. That is His will for us. Do you pray, then? You haven’t mentioned prayer. Do you ask God what is HIS will for you to do?
Are we forgiven or not? Did Crist die for nothing?
