Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? Seest thou how faith wrought with his works, and by works was faith made perfect? 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. Ye see then how that by works a man is justified, and not by faith only. Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way? For as the body without the spirit is dead, so faith without works is dead also.
This scripture gives us two examples of how our faith must be alive with works.
Abraham demonstrated his faith by doing what God said even though it meant putting his only son on the altar. He had faith that God would save Isaac or resurrect him.
Rahab also put feet to her faith when she hid the Israelites and trusted them to keep their word. She could have lost her life, but she trusted God would keep her safe.
Our works show our faith is alive just as our spirit shows our body is alive. Would people come to know Christ if Christians were dead? No! Let us be alive and do good works!
