Gods love is not an emotion. Romans 5:8 God demonstrated/proved/showed His love towards us in that while we were still yet sinners Christ Jesus died for us. John 3:16 For God so loved that He gave His only begotten Son... (speaking of the death of Christ and His sacrifice on the cross.) John 15:13 there is NO greater love than this... than a man lay down his life. (Jesus laid down His life.) God proved His love to ALL of humanity through the sacrificial death... burial and resurrection of Jesus Christ because love... true love... is according to
1 John 4:7 love is of God, love is God. Gods offers us forgiveness of sins, mercy and grace by dying for us because He... God IS love.
