Genesis 16:1 Now Sarai, Abram’s wife, had borne him no children. She had a female Egyptian servant whose name was Hagar. And Sarai said to Abram, “Behold now, the LORD has prevented me from bearing children. Go in to my servant; it may be that I shall obtain children by her.” And Abram listened to the voice of Sarai. So, after Abram had lived ten years in the land of Canaan, Sarai, Abram’s wife, took Hagar the Egyptian, her servant, and gave her to Abram her husband as a wife. And he went in to Hagar, and she conceived. And when she saw that she had conceived, she looked with contempt on her mistress. And Sarai said to Abram, “May the wrong done to me be on you! I gave my servant to your embrace, and when she saw that she had conceived, she looked on me with contempt. May the LORD judge between you and me!” But Abram said to Sarai, “Behold, your servant is in your power; do to her as you please.” Then Sarai dealt harshly with her, and she fled from her.
Sarai, no longer expecting to have children herself, proposed to Abram to take another wife, whose children she might; her slave, whose children would be her property. This was done without asking counsel of the Lord. Foul temptations may have very fair pretences, and be coloured with that which is very plausible. Fleshly wisdom puts us out of God’s way. This would not be the case, if we would ask counsel of God by his word and by prayer, before we attempt that which is doubtful. (Henry)
Abram hearkened to the voice of Sarai; without consulting God about it, the proposal being agreeable to the flesh, which may be imputed to the infirmity of the good man; though it does not appear to arise from previous lust predominant in him; but both Sarai’s proposal, and his compliance with it, might be owing to the eager desire of each after the promised seed; they both believed the promise, but did not know it, being not as yet revealed, that Abram should have a son by Sarai; so that Sarai knowing her own case and circumstances, might conclude it was to be by another, and by her handmaid; and Abram might reason and judge after the same manner, which inclined him to listen to her. (Poole)
As the promise of a lineal heir (Genesis 15:4) did not seem likely to be fulfilled, even after the covenant had been made, Sarai resolved, ten years after their entrance into Canaan, to give her Egyptian maid Hagar to her husband, that if possible she might “be built up by her,” i.e., obtain children, who might found a house or family (Genesis 30:3). The resolution seemed a judicious one, and according to the customs of the East, there would be nothing wrong in carrying it out. Hence Abraham consented without opposition, because, as Malachi (Malachi 2:15) says, he sought the seed promised by God. But they were both of them soon to learn, that their thoughts were the thoughts of man and not of God, and that their wishes and actions were not in accordance with the divine promise.

How long do we wait? Do we wait patiently? Does our faith in the promises of God lessen over time? Waiting on the will and sovereignty of God takes faith. Our faith must grow as time passes on. Never lose site of God’s Promises because of some situation you are experiencing. God is faithful. God is all-powerful. God’s will will be done in His perfect plan and timing for each of our lives. When your faith is tried over and over again, fall on your knees and claim the promises of God and that He will light that fire of faith in your soul to overcome those doubts beating at your faith.
