The good news contained in the part of the Word of God addressed to the believers after the day of Pentecost is that Jesus Christ met all the required conditions so that by confessing Him as Lord and by believing that God has raised Him from the dead you are righteous and saved. This is really good news, is not it? Ephesians tells us:
"For BY GRACE you are saved through faith: and this not from yourselves: it is the GIFT of God: Not by works, so that no-one can boast"
Also Romans 10:9-10
“That if you will confess with your mouth the Lord Jesus, and believe in your heart that God has raised him from the dead, you will be saved. For with the heart man believes unto righteousness; and with the mouth confession is made unto salvation.”
And Acts 16:30-31
“Then he brought them out and said, "Sirs, what must I do to be saved?" And they said, "Believe in the Lord Jesus, and you will be saved, you and your household."
Also: Romans 3:20-24, 28
"Therefore no-one will be declared righteous in his [God's] sight by the works of the law; rather through the law we become conscious of sin. But now the righteousness of God, apart from the law has been made known, to which the law and the Prophets testify. This righteousness of God comes through faith in Jesus Christ to all who believe. For 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 is in Christ Jesus ......Therefore we conclude that a man is justified by faith without the works of the law"
The above passages state that our salvation and our right standing before God, i.e. our righteousness, are not based on how many good works we did, do or will do but on the grace of God. According to the above passages, even if you kept all the law you could not be righteous before God; for as we read: no-one can be righteous before God by the works of the law. And it also says that "all have sinned". Even if you had never sinned in your life (which I’m sure it is not true) there is still Adam's sin which passes down from generation to generation. But praise God, another way has been provided by which we can be righteous before Him. This way is called grace. Yes, someone had to work for all these gifts to be made freely available to us. However, this was neither you nor I but the Lord Jesus Christ. Romans 3 tells us about the accomplishments of Jesus Christ:
"For all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that is in Christ Jesus: whom God set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; he did it to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus."
The redemption is IN CHRIST JESUS, not in what you and I achieved. This is very important if we want to understand the relationship we have with God. Our relationship is based upon the grace of God and the accomplishments of Jesus Christ, NOT upon our worth, works or achievements. We are righteous before God twenty four hours a day. The reason is that this right standing was given to us by grace. It was given to us as a result of the unmerited favor and love that God has for us. It is "righteousness of God", NOT righteousness from ourselves i.e. self righteousness. This "of" denotes the source of this righteousness. This source is neither you nor I but God. Galatians 2:16 also tells us:
"know that a man is not justified by the works of the law but by faith in Jesus Christ. So we too have put our faith in Christ Jesus that we may be justified by faith in Christ and not by the works of the law: for by the works of the law no-one will be justified."
Once more we see that a man is not justified by the works of the law but by faith in Jesus Christ! If it was by works, I could say: "Look I did more than you. I deserve it more than you." No-one deserved something from God. It was God who, motivated by His love for us, sacrificed His Son so that by believing in Him we can be righteous and saved. That's really grace! Amazing grace!
