Genesis 22:16 And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son: 17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; 18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
God had already made great promises to Abraham that he would be blessed and be a blessing. But what I notice in this verse is that his obedience caused God to promise again. God said, because you have done this, because you did not hold back your son then I have even more for you.
I know that I have great promises from God. I know that He has been good to me and is going to be good to me. I do think this verse would indicate that my obedience can bring more of God’s blessings on me. I want to be obedient. I want to please Him. I know He is pleased. I know that He loves me in spite of any and everything but I love Him so much that I want to do what He wants me to do!
