Love Is Self-Sacrificial

From Trusting God: Even When Life Hurts by Jerry Bridges, p138:

The extent of God's love at Calvary is seen in both the infinite cost to Him of giving His one and only Son, and in the wretched and miserable condition of those He loved. God could not remove our sins without an infinite cost to both Himself and His Son. And because of their great love for us, both were willing--yes more than merely willing--to pay that great cost, the Father in giving His one and only Son, and the Son in laying down His life for us. One of the essential characteristics of love is the element of self-sacrifice, and this was demonstrated for us to its ultimate in God's love at Calvary.
