Paul wrote that Abraham was their “forefather according to the flesh.” Some scholars think Paul wanted to say that Abraham was the ancestor of every Jew. Other scholars think this was a metaphor. Paul wanted to say anyone who believed in God was a descendant of Abraham (see: Romans 4:11, 16).
See: Matthew 3:9; John 8:53, 56; Acts 13:26; 2 Corinthians 11:22
Paul wrote about “boasting”(καύχημα/g2745). He was speaking about some who said they were righteous. This dishonored God because they were not righteous. Every person is a sinner. While Abraham did many good things, he could not be at peace with God by being righteous. Only God could give him righteousness and peace.
Abraham was written about in the Old Testament. Paul wanted people to know that the gospel agreed with the Old Testament. Abraham trusted God. Christians should also trust God.
See: Psalm 106:31; 2 Corinthians 5:19; Galatians 3:6-8; James 2:23
Paul wrote the same thing as David in Psalm 31:1-2. David was very happy God forgave him after his sin with Bathsheba. Paul was also very happy that God forgave him.
David often sinned. God forgave him even though David didn’t deserve it. In the Bible, sins were covered before Jesus died. This changed when Jesus died. God did not count people sins. That is, people were at peace with God even though they sinned because Jesus died.
Paul wrote that circumcision was a “seal of righteousness. That is, Abraham was circumcised because he believed in God and was at peace with God. He was not at peace with God because he was circumcised, but because he had faith in God.
Advice to Translators: This might be translated as “circumcision was the physical proof that he was already righteous.”
Paul wrote that Abraham was the father of all. He was not an ancestor of everyone who believes in Jesus. However, people who believe in Jesus do the same types of things Abraham did (see: Romans 4:1). They believe in God in the same way Abraham believed in God.
Someone who walked in the footsteps of someone else did the same types of things the other person did. This was a metaphor. People did the same types of things Abraham did.
See: Proverbs 2:20; John 8:39-40; 2 Corinthians 12:18; 1 Peter 2:21
God promised Abraham that he would be the “heir” (κληρονόμος/g2818) of the world. That is, he and his descendants would eventually become the owners of the whole world.
Paul wrote about faith being made empty and a promise made void. He meant that having faith in God would not have any value, and God’s promise would be broken. He was speaking about something as if it could happen, but it could not happen.
Paul wrote that there is no transgression when there was no law. A “transgression”(παράβασις/g3847) was a certain type of sin, where someone disobeyed a command of God. If there was no Law of Moses, people would still sin, but they would not be disobeying God’s commands because they did not know the Law of Moses.
Paul wrote that the promise rested on grace. That is God gives people what he promised through the grace that he gave to people, not through them obeying the Law of Moses.
Paul wrote that Abraham was the father of many nations. This is something God promised to Abraham (see: Genesis 17:4). Some scholars think Paul was speaking about how all Christians inherit the promises God gave to Abraham. Other scholars think that Christians do not inherit these promises, but they do the same types of things Abraham did.
God called things that do not exist into existence. That is, God made things from nothing. He did this just by speaking. He made everything in the universe by speaking.
Abraham believed in him and against hope. He was confident that God would do everything he promised. He did this even when people did not think God could do the things he promised.
See: Ruth 1:12; Psalm 39:7; Romans 15:13; 1 Peter 1:3
Paul wrote that Abraham’s body and Sarah’s womb were dead. They were not dead. This was a metaphor. They were too old to have children. Abraham was 99 years old (see: Genesis 17:1). Sarah was very old and past the age when she could have children (Genesis 18:11).
Paul wrote that Jesus was raised for our justification. That is, Jesus was resurrected so that Christians can be at peace with God. Jesus needed to be resurrected (see: Romans 10:9-10; Romans 5:12-21; 1 Corinthians 15:45).
