And thou saidst, I will surely do thee good. Genesis 32:12
"WHEN Jacob
was on the other side of the brook Jabbok, and Esau was coming with
armed men, he earnestly sought God's protection, and as a master reason
he pleaded, "And Thou saidst, I will surely do thee good."
---Oh, the force
of that plea! He was holding God to His 
word—"Thou saidst."
---The
attribute of God's faithfulness is a a splendid horn of the altar to lay
hold upon; but the promise, which has in it the attribute and something
more, is a yet mightier holdfast—"Thou saidst, I will surely do thee
good."
Q: And has He said, and shall He not do it?
---When a man
gives a promissory note, his honor is engaged; he signs his hand, and
he must discharge it when the due time comes, or else he loses credit.
---It shall never be said that God dishonors His bills. The credit of the
Most High never was impeached, and never shall be. He is punctual to the
moment: He never is before His time, but He never is behind it."
Charles Spurgeon
