"What shall I render unto the LORD for all his benefits toward me? I will take the cup of salvation, and call upon the name of the LORD." (Psalm 116:12-13)
Here is a remarkable question and answer. To every one born into the world, God has given multitudes of benefits. "He giveth to all life, and breath, and all things" (Acts 17:25). Some receive more than others, but all receive many, so the question is what we should do for the Lord in return. The answer is simply to receive His great gift of eternal salvation!
On one occasion the people of Capernaum asked Jesus: "What shall we do, that we might work the works of God?" His answer must be profoundly surprising to anyone who believes that he can please God and earn salvation by doing good works. "This is the work of God," said Jesus, "that ye believe on him whom he hath sent" (John 6:28-29).
The truth is we can never pay for our sins by good deeds. If one is ever to be saved from his sins and to obtain salvation, it must be received solely by faith in the work of the Lord Jesus Christ. "For the wages of sin is death," but "while we were yet sinners, Christ died for us," so that "the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many" and--in the words of our text above--"whosoever shall call upon the name of the Lord shall be saved" (Romans 6:23, 5:8, 5:15, 10:13).
Therefore, when a repentant sinner calls in faith on the wonderful name of our gracious Lord, he drinks of the healing cup of salvation and receives everlasting life. Because Jesus drank the bitter cup of God’s righteous judgment on our sins, we can drink deeply of the "living water. . . . springing up into everlasting life" (John 4:10-14), and we can say with the psalmist: "My cup runneth over. Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever" (Psalm 23:5-6). HMM
