This is Righteousness by Faith
And what is it to believe? It is to fully accept that Jesus Christ died as our sacrifice; that He became the curse for us, took our sins upon Himself, and imputed unto us His own righteousness. Therefore we claim this righteousness of Christ, we believe it, and it is our righteousness. He is our Saviour. He saves us because He said He would. Are we going to go into all the explanations as to how He can save us? Do we have the goodness in ourselves that will make us better and cleanse us from the spots and stains of sin, enabling us then to come to God? We simply cannot do it.FW 70.2
Don't you know that when the young man came to Christ and asked Him what he should do that he might have life, Christ told him to keep the commandments. Said he, “I have done it.” Now the Lord wanted to bring this lesson right home. “What lack I yet? I am perfectly whole” (Matthew 19:20). He did not see that there was a thing the matter with him or why he should not have eternal life. “I have done it,” he said. Now Christ touches the plague spot of his heart. He says, “Come, follow Me, and ye shall have life.”FW 70.3
What did he do? He turned away very sorrowful, for he had great possessions.FW 70.4
Now he had not kept the commandments at all. He should have accepted Jesus Christ as his Saviour and taken hold of His righteousness. Then, as he had the righteousness of Christ, he could keep the law of God. The young ruler could not trample that law under his feet. He must respect it; he must love it. Then Christ would bring divine power to combine with man's efforts.FW 70.5
Christ took upon Himself humanity for us. He clothed His divinity, and divinity and humanity were combined. He showed that that law which Satan declared could not be kept, could be kept. Christ took humanity to stand here in our world, to show that Satan had lied. He took humanity upon Himself to demonstrate that with divinity and humanity combined, man could keep the law of Jehovah. Separate humanity from divinity, and you can try to work out your own righteousness from now till Christ comes, and it will be nothing but a failure.FW 71.1
By living faith, by earnest prayer to God, and depending upon Jesus’ merits, we are clothed with His righteousness, and we are saved. “Oh, yes,” some say, “we are saved in doing nothing. In fact, I am saved. I need not keep the law of God. I am saved by the righteousness of Jesus Christ.” Christ came to our world to bring all men back to allegiance to God. To take the position that you can break God's law, for Christ has done it all, is a position of death, for you are as verily a transgressor as anyone.FW 71.2
Then what is it? It is to hear and to see that with the righteousness of Christ which you hold by faith, righteousness supplied by His efforts and His divine power, you can keep the commandments of God.FW 71.3
