Even though God had said to him, “It is through Isaac that your offspring will be reckoned.” Abraham reasoned that God could even raise the dead, and so in a manner of speaking he did receive Isaac back from death. – Hebrews 11:19

Faith is not erratic. It is absolute trust in the God who is unchanging. Abraham’s faith attests to this.

The man had received the promise of his life from God in Haran.

“I will make you into a great nation.” (Genesis 12:2).

At seventy-five, Abraham left for the unknown country God had called him to.

“I will give this land to your descendants,” God promised Abraham(7).

Years passed, and Abraham had no child. The faithful God, who knows when we are failing, said to Abraham in a dream:

“Do not be afraid, Abram, for I will protect you, and your reward will be great” (15:1).

Abraham considered his childlessness and age and surmised that his servant would become his heir. But that was not the intention of God (Genesis 15:1-4).

Then the Lord took Abram outside and said to him, “Look up into the sky and count the stars if you can. That’s how many descendants you will have!” (5).

Abraham is one hundred years old now, and he is holding Isaac, the promised child from Sarah, his ninety-year-old wife (21:2). Isn’t God good? He is Amazing!

God’s faithfulness had its anchor on His immutability. It is what makes Him trustworthy and reliable. Balaam stated this so well:

“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?” (Nu. 23:19).

Writing to his young protégé, Timothy, the Apostle Paul wrote:

“If we are faithless, He remains faithful, for He cannot disown Himself” (2 Tim. 2:13).

It is the very nature of God to be true to Himself. When we come to faith in Jesus, this should be the basis of our walk with Him. His faithfulness should anchor our faith and put our minds at rest in Him. Jesus implies this in His invitation to the wearied soul. 

“Come to me, all you who are weary and burdened, and I will give you rest” (Matt. 11:28).

The believer’s trust must remain steadfastly set in Christ against every gale and storm. Fear and doubt have no place in the Christian faith. So, anytime fear and doubt assail us—for whatever reason—our instinct should recall God’s faithfulness to help settle our mind and bring us His peace in Christ.

Years later, God tested Abraham with the offering of Isaac. But Abraham prevailed.

Abraham reasoned that God could even raise the dead, and so in a manner of speaking, he did receive Isaac back from death” (Hebrews 11:19).

That is the unwavering trust God commends and blesses with His glory. It settles the heart in the Prince of Peace. Isaiah alludes to this assurance of peace in Isaiah 26:3:

“You will keep in perfect peace those whose minds are steadfast because they trust in you.”

So, no matter your situation or circumstance, set your mind on Christ and trust Him until the storm passes. Do not allow cynicism to obscure the faithfulness of God. Remember that the arm of flesh will fail you (2 Chron. 32:8), but the mighty hand of God, which compelled Pharaoh to let go of His people, shall surely deliver His promise to you (Ex. 3:19).
