The sons and daughters of God are not spared from their crosses; God does not rescue His own from all of the sufferings of life.  He even calls on us to make a living sacrifice of ourselves to Him.  “Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship.” Romans 12:1 (NASB).  In the light of the sacrifice of Christ, the great mercy-of-God act, I live a life of sacrifice which is my worship.  Our Elder Brother took up His cross; as an act of love, we gladly take up ours as the un-spared sons and daughters of God.
