For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. – Romans 6:23

Nothing is freer than a gift: “the gift of God is eternal life.” He has given us all things for nothing, that we might behold the exceeding riches of His grace… The Lord God has a right to give what He pleases, for “the earth is the Lord’s, and the fullness thereof; the world, and they that dwell therein.” Of His own has He given unto us. In the great sacrifice of His dear Son He has satisfied all claims of justice, and He acts justly when He blesses largely those for whom Jesus died. When a man has the freehold of his land, he has a right to give it away if so it pleases him. The Most High God is possessor of all things, and when He says to His people “I give you this,” who shall dispute His right? The blessings of the covenant of grace are a royal gift: they come to us by divine right. Who shall question Jehovah’s will? He asks peremptorily, “Shall I not do as I will with My own?” That which grace has given us is ours by a surer title than anything else can ever be.

God gives Christ and His grace to us every day. The blessings of the covenant are continually fresh gifts of His hand. By two immutable things wherein it is impossible for God to lie, He has made over the covenant possessions to us, and if it were to be done again He would do it without hesitation. “The gifts and calling of God are without repentance.” “I do give,” saith He, and thus He stands to His act and deed. ~ C.H. Spurgeon
