Our God is Love. Everything He does is motivated by His love for mankind. When He chastises, it is out of love for the person. Every Father that loves his child disciplines him; our God loves more than any father. He even gave His only son for mankind all because of His love. What god will sacrifice his ONLY son for any reason?
When you accept Jesus, the son of God, you accept Gods love for you. The beauty of salvation is that Gods love is poured into your heart when you welcome Jesus into your heart. You are able to love people even as God loves you. Actually, if you do not love then you do not know God!
The God we serve loves unconditionally. No matter how much evil you may have committed, when you come to Him, He accepts you. He gave Jesus when we were deep in our sins so that we will not suffer eternal death if we receive Jesus as our Lord.
