A few years ago I was debating someone on another debate site concerning whether salvation was by grace or whether it was by works. The person I was debating was saying that we must obey The Mosaic Law in order to be saved, while I was saying that we must accept salvation as a free gift (by grace) in order to attain it.
What neither of us knew was that a Jewish scholar had paid a visit to the Christian debate site and was looking over our shoulders as we were debating. After he read our posts,he introduced himself to us. Then he proceeded to teach both of us what the Torah says is to be seen as the reward for obeying the Mosaic Law. This is that passage:
"If you pay attention to these laws and are careful to follow them, then the Lord your God will keep his covenant of love with you, as he swore to your forefathers. He will love you and bless you and increase your numbers. He will bless the fruit of your womb, the crops of your land - your grain, new wine and oil - the calves of your herds and the lambs of your flocks in the land that he swore to your forefathers to give you. You will be blessed more than any other people; none of your men or women will be childless, nor any of your livestock without young. The Lord will keep you free from every disease. He will not inflict on you the horrible diseases you knew in Egypt, but he will inflict them on all who hate you." (Deuteronomy 7:12-15,NIV)
That's it; that is what God agreed to do for the Hebrew people if they followed his laws and commandments. It was a pragmatic, here-and-now contract, with all rewards for their obedience given to them in this lifetime.
Jesus Christ himself nullified any thoughts of our earning our own way into heaven. He taught his disciples that they were never to see their own actions as earning them any points with God:
"Suppose one of you had a servant plowing or looking after the sheep. Would he say to the servant when he comes in from the field, 'Come along now and sit down to eat'? Would he not rather say, 'Prepare my supper, get yourself ready and wait on me while I eat and drink; after that you may eat and drink'? Would he thank the servant because he did what he was supposed to do? So you also, when you have done everything you were told to do, should say, 'We are unworthy servants; we have only done our duty.' " (The Gospel According to St. Luke 17:7-10,NIV)
What we do, no matter what it is or to what extent we do it, is to be seen as nothing more than what we were supposd to do. We are not to expect to earn points with God, buy our own ticket to heaven, get stars in our crowns, or any other reward. Our only reward is to be the recognition of the task as having been accomplished. Then we are to proceed to the next task.
But the Jewish scholar and we Christians agreed that the only way for us to enter God's presence was to be through God's infinite mercy. Except for Jesus Christ himself, no one has been perfect. And perfection is what is required of those who would earn their own way into God's presence. There is no such thing as 'good enough'. St. Paul wrote concerning this, telling us plainly where we stood, and then telling us what God himself had done to rescue us from our own shortcomings:
"Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin."
"But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify. This righteousnes from God comes through faith in Jesus Christ to all who believe. There is no difference, for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus. God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished - he did it to demonstrate his justice at the present time, so as to be just and the one who justifies those who have faith in Jesus." (Romans 3:19-26,NIV)
The salvation that is necessary for us to enter God's presence is a salvation that God himself has provided for us. He drew up the blueprint, and through his son Jesus Christ he fulfilled the atoning sacrifice necessary for our salvation. He is the Author of Justice; he is also the Epitome of Mercy. Through God, rather than through our own works, is our salvation achieved. What we do in return for this salvation is to be recognized as nothing more than a feeble thank you.
