James 2:21 says, Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? James then gives the example of Abraham being willing to offer Isaac as a sacrifice. This was a work, or action, that Abraham took in obedience to God, and it showed his faith.
Verse twenty-two adds, Seest thou how faith wrought with his works, and by works was faith made perfect? James asked could they not see that Abraham's faith led him to do this and by his willingness to do what God asked, he proved his faith in God. If we say we have faith but are unwilling to do something that God calls us to do, then where is our faith.
Verse twenty-three continues, And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. James said that Abraham believed God when He asked him to take Isaac up the mountain to offer as a sacrifice out of faith in God, and because he was willing to put his faith in God, he was known as a Friend of God. If we want to be known as a friend of God, we must put our faith into action when God calls us to do something, even if we don't know what the outcome will be.
Verse twenty-four concludes, Ye see then how that by works a man is justified, and not by faith only. James then asked if we cannot see that we are justified by putting our faith into action and not by just professing that we have faith and having nothing in our life change. We are saved by faith in Jesus Christ alone, but once we are saved, our faith should be shown by our works, or the way we live our life.
Verse twenty-five states, Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way? James then asked if the actions, or work, of Rahab the harlot had not justified her, since her action in helping the spies was based on her faith in God. Many of the people of Israel professed to have faith in God, but they were unwilling to live by that faith. Their lack of works proved their faith to either be weak or false.
Verse twenty-six adds, For as the body without the spirit is dead, so faith without works is dead also. James said just as our body without the spirit is dead, so is faith without works. We cannot see our spirit, but as long as we are live we know that it is there, and our actions prove this. It is the same with faith being shown by our works, even if faith cannot be seen physically.
