Chapter 4 of Romans describes how Abraham was accounted righteous solely because of faith — by believing that God would provide him and Sarah with a child even though they were very advanced in age. These verses paint a picture of a godly man firmly rooted in a strong faith who did not waver with unbelief. He was not a perfect person, but he strove to have a walk of faith and to maintain hope in the promise that God made to him.
We may not all measure up to the strength of Abraham’s faith, but thankfully it is not the strength of our faith that saves us; we are saved by the object of our faith: God who raised up Jesus our Lord from the dead (Romans 4:24). The work is all God’s, through Christ Jesus, so that we have nothing of which to boast (Romans 4:2). Praise God that He loved us even while we were sinners, and sent Jesus to die for us (Romans 5:8). He promises to us eternal life if we simply place our faith in Christ Jesus. Then, like Abraham, we will be accounted righteous, simply by believing God’s promise.
