By faith Abraham obeyed when he was called to go out to a place that he was to receive as an inheritance. And he went out, not knowing where he was going.  By faith he went to live in the land of promise, as in a foreign land, living in tents with Isaac and Jacob, heirs with him of the same promise.  For he was looking forward to the city that has foundations, whose designer and builder is God.  By faith Sarah herself received power to conceive, even when she was past the age, since she considered him faithful who had promised.  Therefore from one man, and him as good as dead, were born descendants as many as the stars of heaven and as many as the innumerable grains of sand by the seashore. (Hebrews 11:8-12 (ESV)
Faith leads to works. Works do not lead to faith. Without faith it is impossible to obey God, even when you are trying to live by the Ten Commandments. If you were to read much of the evangelical literature, you might be led to believe you don’t have faith, because your works aren’t enough. Or even worse, you might be led to believe you have faith because of your works. However, it is knowing that Jesus Christ died for your sins, that God is faithful to forgive, that leads to works, and if you have these you do have works pleasing to God. You just do. Changing the baby’s diaper is a good work there.
