When God makes a promise by whom shall He swear that He will keep His promise? Listen to the Hebrew writer,
“For when God made a promise to Abraham, because He could swear by no one greater, He swore by Himself, saying, ‘Surely blessing I will bless you, and multiplying I will multiply you’” (Hebrews 6:13–14).
Then all that has to be done next is to see whether He does it. Did He do as promised to Abraham? Yes, He did. What promises has He made to us Christians? Whatever those promises are, He will keep them, such as promising to be with us as we go through death, or to forgive us when we repent, confess our sins, and ask for His forgiveness, and many other promises.
