Now, a great many people want some token outside of God's word. That habit always brings doubt. If I made a promise to meet a man at a certain hour and place to-morrow, and he were to ask me for my watch as a token of my sincerity, it would be a slur on my truthfulness. We must not question what God has said: He has made statement after statement, and multiplied figure upon figure. Christ says: "I am the door; by Me if any man enter in he shall be saved." "I am the Good Shepherd, and know My sheep, and am known of Mine." "I am the light of the world; he that followeth Me shall not walk in darkness, but shall have the light of life." "I am the truth;" receive Me, and you will have the truth; for I am the embodiment of truth. Do you want to know the way? "I am the way:" follow Me, and I will lead you into the kingdom. Are you hungering after righteousness? "I am the Bread of life:" if you eat of Me you shall never hunger. "I am the Water of life:" if you drink of this water it shall be within you "a well of water springing up unto everlasting life." "I am the resurrection and the life: he that believeth in Me, though he were dead, yet shall he live; and whosoever liveth and believeth in Me shall never die." (John xi. 25, 26.)
Let me remind you where our doubts come from. A good many of God's dear people never get beyond knowing themselves servants. He calls us "friends." If you go into a house you will soon see the difference between the servant and the son. The son walks at perfect liberty all over the house; he is at home. But the servant takes a subordinate place. What we want is to get beyond servants. We ought to realize our standing with God as sons and daughters. He will not "un-child" His children. God has not only adopted us, but we are His by birth: we have been born into His kingdom. My little boy was as much mine when he was a day old as now that he is fourteen. He was _my son_; although it did not appear what he would be when he attained manhood. He is mine; although he may have to undergo probation under tutors and governors. The children of God are not perfect; but we are perfectly His children.
Another origin of doubts is looking at ourselves. If you want to be wretched and miserable, filled with doubts from morning till night, look at yourselves. "Thou wilt keep him in perfect peace whose mind is stayed on Thee." (Isa. xxvi. 3.) Many of God's dear children are robbed of joy because they keep looking at themselves.
Some one has said: "There are three ways to look. If you want to be wretched, look within; if you wish to be distracted, look around; but if you would have peace, look up." Peter looked away from Christ, and he immediately began to sink. The Master said to him: "O thou of little faith! Wherefore didst thou doubt?" (Matt. xiv. 31.) He had God's eternal word, which was sure footing, and better than either marble, granite or iron; but the moment he took his eyes off Christ down he went. Those who look around cannot see how unstable and dishonoring is their walk. We want to look straight at the "Author and Finisher of our faith."
When I was a boy I could only make a straight track in the snow, by keeping my eyes fixed upon a tree or some object before me. The moment I took my eye off the mark set in front of me, I walked crooked. It is only when we look fixedly on Christ that we find perfect peace. After He rose from the dead He showed His disciples His hands and His feet. (Luke xxiv. 40.) That was the ground of their peace. If you want to scatter your doubts, look at the blood; and if you want to increase your doubts, look at yourself. You will get doubts enough for years by being occupied with yourself for a few days.
Then again: look at what He is, and at what He has done; not at what you are, and what you have done. That is the way to get peace and rest.
Abraham Lincoln issued a proclamation declaring the emancipation of three millions of slaves. On a certain day their chains were to fall off, and they were to be free. The proclamation was put up on the trees and fences wherever the Northern Army marched. A good many slaves could not read: but others read the proclamation, and most of them believed it; and on a certain day a glad shout went up, "We are free!" Some did not believe it, and stayed with their old masters; but it did not alter the fact that they were free. Christ, the Captain of our salvation, has proclaimed freedom to all who have faith in Him. Let us take Him at His word. Their feelings would not have made the slaves free. The power must come from the outside. Looking at ourselves will not make us free, but it is looking to Christ with the eye of faith.
Bishop Ryle has strikingly said: "Faith is the root, and Assurance the flower." Doubtless you can never have the flower without the root; but it is no less certain you may have the root, and not the flower.
