…I will not turn away from them, to do them good… – Jeremiah 32:40

He hath given meat unto them that fear Him: He will ever be mindful of His covenant. – Psalm 111:5

If the Lord’s chosen and redeemed are cast away, where is the glory of His redemption? Will not the enemy say of the Lord, “He had not the power to carry out His covenant, nor the constancy to continue blessing them”? Shall that ever be said of God? Will He thus lose the glory of His omnipotence and immutability? I cannot believe that any purpose of the Lord can fail; neither can I conceive that He can withdraw His declarations of love to those with whom He is in covenant. The God whom we adore and reverence, the God of Abraham, the God and Father of our Lord and Saviour Jesus Christ, fainteth not, neither is weary. “He is in one mind, and who can turn Him?” “He will ever be mindful of His covenant.” Of our Lord Jesus we truly sing-

“His honour is engaged to save
The meanest of His sheep;
All that His heavenly Father gave,
His hands securely keep.”

Whether my arguments seem good to you or not, is of small consequence; for the text is the inspired Word of God, and it cannot be misunderstood or questioned. Thus saith the Lord, “I will not turn away from them, to do them good.” ~ C.H. Spurgeon
