Question 1

What does it mean when God says, "I am the Almighty God; walk before me, and be thou perfect"?

Accepted Answer

When God calls Himself the Almighty God, He is saying He has all power and is fully able to keep His promises. By telling Abraham to “walk before me,” God is calling him to live every part of his life in God’s sight, with a steady trust and open obedience. “Be thou perfect” does not mean Abraham must be without any sin, but that he should be sincere, whole-hearted, and upright. God’s covenant love comes first, and Abraham’s honest, obedient life is the fitting response to that grace.

Question 2

Why did God change Abram’s name to Abraham and Sarai’s name to Sarah?

Accepted Answer

God changed Abram’s name, which meant something like “exalted father,” to Abraham, meaning “father of many nations,” to match the promise He was making. God was not just commenting on Abraham’s present life, but on what He Himself would bring about through him. In the same way, Sarai’s name is changed to Sarah as God promises to bless her, give her a son, and make her “mother of nations.” The new names are like a seal and reminder of God’s promise to both of them.

Question 3

What is the significance of circumcision as the sign of the covenant?

Accepted Answer

Circumcision was given as the outward sign that Abraham and his descendants belonged to God’s covenant. It marked every male in the family, whether born in the house or bought, showing that the whole community was set apart for God. It was done on the private part to picture that what humans pass on is sinful and needs cleansing. The act itself did not save, but it pointed to God’s promise and called for an inward change of heart. Refusing circumcision was treated as despising both the sign and the promise.

Question 4

Why was the uncircumcised male child to be cut off from his people?

Accepted Answer

God says that any male who refused circumcision had broken His covenant and would be cut off from his people. This shows how seriously God treated His sign. To reject the sign was like refusing the covenant itself and turning away from God’s promise and rule. Since circumcision marked belonging to God’s people, staying uncircumcised was choosing to stand outside that family. This teaches that God’s promises come with a real call to obedience, not as empty words but as a lived relationship with Him.

Question 5

How are Isaac and Ishmael different in God’s covenant in this passage?

Accepted Answer

In this chapter God makes it clear that Isaac will be the child through whom He establishes His special, everlasting covenant. Isaac is the promised son, born to Abraham and Sarah at the time God sets. God still blesses Ishmael, promising to make him fruitful and a great nation with twelve princes. But He says, “My covenant will I establish with Isaac.” So Ishmael receives real earthly blessings, while the main covenant line and the promise of a lasting relationship with God are tied especially to Isaac and his descendants.

Question 6

Why did Abraham laugh when God promised a son through Sarah?

Accepted Answer

Abraham fell on his face and laughed when God said Sarah would bear him a son, because the promise came when he was about a hundred and Sarah about ninety. His laughter flowed from a mix of wonder and joy at something that seemed humanly impossible, not from cold unbelief. He even cried out that Ishmael might live before God, showing his care for the son he already had. God answers kindly, repeating the promise of Isaac and setting his name, and also assuring Abraham that Ishmael will be blessed too.

Question 7

What does this passage teach about God’s character and His covenant?

Accepted Answer

This passage shows God as the Almighty who keeps His word even when it seems too late from a human point of view. He patiently renews His covenant with Abraham, gives clearer promises, and even changes names to underline what He will do. The covenant is called everlasting, with God promising to be God to Abraham and his seed after him, to give them land, and to make nations and kings come from them. At the same time, God calls for real obedience, shown in walking before Him and keeping His covenant sign.

Question 8

Why did God wait until Abraham was ninety-nine to renew the covenant and promise Isaac?

Accepted Answer

The long wait, including the years after Ishmael’s birth, shows that God works on His own timetable, not ours. With Abraham and Sarah both very old, it became clear that the promised child would come only by God’s power, not by human strength or planning. The delay also trained Abraham to depend more on God’s promise instead of resting in what he already saw in Ishmael. When God finally speaks again, He makes His almighty power and free grace very clear by promising a son through Sarah at a set time.

Question 9

How did Abraham respond to God’s command about circumcision, and what does that show?

Accepted Answer

Abraham obeyed at once. The passage says that on the very same day God spoke, Abraham was circumcised, along with Ishmael and every male in his household, whether born there or bought. This quick and complete obedience shows his faith was real and active. He did not only accept the promises; he also accepted the cost and the duty that came with them. It also shows his role as leader in his home, teaching and guiding all under his care to follow what God had said.
