John 14:5-6
“Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.”
“The condition of eternal life is now just what it always has been,—just what it was in Paradise before the fall of our first parents,—perfect obedience to the law of God, perfect righteousness. If eternal life were granted on any condition short of this, then the happiness of the whole universe would be imperiled. The way would be open for sin, with all its train of woe and misery, to be immortalized.
It was possible for Adam, before the fall, to form a righteous character by obedience to God’s law. But he failed to do this, and because of his sin our natures are fallen and we cannot make ourselves righteous. Since we are sinful, unholy, we cannot perfectly obey the holy law. We have no righteousness of our own with which to meet the claims of the law of God. But Christ has made a way of escape for us. He lived on earth amid trials and temptations such as we have to meet. He lived a sinless life. He died for us, and now He offers to take our sins and give us His righteousness. If you give yourself to Him, and accept Him as your Saviour, then, sinful as your life may have been, for His sake you are accounted righteous. Christ’s character stands in place of your character, and you are accepted before God just as if you had not sinned.” Steps to Christ p.63
