There is no searching of His understanding. The Lord's memory is toward the little in Israel. He carrieth the lambs in His bosom. We are liable to fret a little when we think of our changeableness . Even Elijah, who was so brave, had his fainting fits.
Redemption is a fact accomplished.
The Cross, it standeth fast. The price is paid, the ransom accepted. This is done, and can never be undone. Change of feeling within does not alter the fact that the believer has been bought with a price, and made the Lord's own by the precious blood of Jesus. The Lord God has already done so much for us that our salvation is sure in Christ Jesus.
