He told us all that the Father told Him. The Father loved the Son. He saved Him from sin, death and the devil. The Son loved all men. As their substitute He saved them from sin, death and the devil.
Christians love each other.
They do, say and think what is best for each other. Christians love God by trusting in Him. The love of the Father equipped Christ and saved Him. The love of Christ for the world redeemed the world. And the love of Christian for Christian is a gift of God whereby they serve each other.
