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 LORD. The key is in the taking of what God has for me. I take purity. I take love. I take wisdom, grace, patience, and kindness.
A person who gets angry all the time doesn't need to learn how to control his temper; he needs to take meekness from the life of Jesus Christ through the Spirit. He doesn't have to change; he has to take something to replace the anger. A man doesn't have to overcome lust; he just has to take purity. Purity doesn't lust. It is received from the cup of salvation. Having a disciplined schedule is something we take from God's order of respect and responsibility of love.
What does a man render to God for all of His benefits? The Psalmist didn't say, "I will do…." He said, "I will take His life from the cup of salvation." The cup represents your capacity for God. This means when you don't have something you need and you're feeling spiritually bankrupt, just drink what you need from the cup.
What was in the cup is now inside of you! The cup contains what you need for your situation today.
