1 When Abram was ninety-nine years old, the LORD appeared to him and said, “I am God Almighty; walk before me and be blameless.

2 I will confirm my covenant between me and you and will greatly increase your numbers.”

3 Abram fell facedown, and God said to him,

4 “As for me, this is my covenant with you: You will be the father of many nations.

5 No longer will you be called Abram; your name will be Abraham, for I have made you a father of many nations.

6 I will make you very fruitful; I will make nations of you, and kings will come from you. Genesis 17:1-6 NIV

15 God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah.

16 I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.” Genesis 17:15-16 NIV

19 Then God said: “No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him. Genesis 17:19 NIV

1 Now the LORD was gracious to Sarah as he had said, and the LORD did for Sarah what he had promised.

2 Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. Genesis 21:1-2 NIV

The Lord always fulfills His promises. He always does exactly what He says that He will do. It took twenty-five years from the time God spoke to Abraham and promised him a son who would be the first of a multitude of descendants, until the fulfillment of that promise, but it did come to pass exactly as He had said.

God made the promise – Abraham tried to help God by fathering a child by Sarah’s servant – but this was not God’s plan. Sarah was Abraham’s wife. Sarah was to be the mother of the promised child. Over the years Abraham’s faith in God’s word to him grew stronger and stronger until finally, after all those years, Sarah conceived and Isaac was born.

I will cry unto God Most High, Who performs on my behalf and rewards me [Who brings to pass His purposes for me and surely completes them]! Psalms 57:2 AMP

God has a plan for us. He performs on our behalf. He does those things that He said He would. He rewards us by bringing to pass His purposes for us. Not only does He begin His work in our lives, but He also completes it.

He follows through with His promises. He does everything that He says He will do. He will never let us down or take us only half way. He will take us all the way. If He said it – He will do it! He will fulfill His promises to us.

Numbers 23:19 NKJV says, “God is not a man, that He should lie, nor a son of man, that He should repent. Has He said, and will He not do? Or has He spoken, and will He not make it good? The NIV says, “God is not a man, that He should lie, nor a son of man, that He should change his mind. Does He speak and then not act? Does He promise and not fulfill?”

If God said it – you can take it to the bank! If He said it – you can believe it and you can act on it.

10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:

11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. Isaiah 55:10-11 KJV

When God speaks a word, when He makes a promise, it never comes back to Him empty, useless or void, without producing any effect. God’s Word always accomplishes what He pleases, purposes and desires. It always prospers everywhere He sends it. It always achieves the purpose and succeeds in the matter for which He sent it – it always produces fruit!

In Luke 1:37 KJV, the angel tells Mary, “For with God nothing shall be impossible.” The ASV says, “For no word from God shall be void of power” and the TLB says, “For every promise from God shall surely come true.” Mary says to the angel in verse

38, “Behold the handmaid of the Lord; be it unto me according to thy word. I am the Lord’s servant, and I am willing to do whatever he wants. May everything you said come true.” Because Mary immediately believed God’s Word and received God’s Word, she conceived by the Holy Spirit and nine months later she gave birth to Jesus, the spotless Lamb of God. How wonderful for us that she was a godly woman, who took God at His Word so that now we can receive God’s promise too. God’s Word is powerful and His promises are true.

God’s Word never returns to Him void – without accomplishing His purpose and succeeding in its mission. Will you believe the Word that God has spoken to you? Will you receive the fulfillment of His promise to you? God always keeps His Word. Will you believe His Word and so see it manifested in your life?
