It is a wonderful fact of human nature that we learn far more easily from example than we do in any other way. Now, you have in this passage an example of a sinner saved by faith. It shows you how a sinner is saved. And as Noah fled into the ark which he had prepared, so should you. You too, have an ark provided; and just as Noah thereby condemned the world - that is, shewed that the world was righteously condemned so will you; if you enter in, you will show by your faith that its condemnation is just.
Let us go over these things and see:
First, Noah's warning: "By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house." We have an account given us of the warning of Noah in the 6th chapter of Genesis:
And it came to pass, when men began to multiply on the face of the earth ... that the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose. And the LORD said, My Spirit shall not always strive with man, for that he also is flesh; yet his days shall be an hundred and twenty years; verses 1-3.
That was the first warning.
And the LORD said, I will destroy man, whom I have created from the face of the earth; both man and beast and the creeping thing, and the fowls of the air; for it repenteth me that I have made them; verse 7.
This is the second warning. That was the warning which God gave Noah; he told him that the Holy Spirit would not always strive with man, and then he told him that he would destroy man whom he had created. Now, if Noah had been like some of you, he might have said, God is a merciful God - he will not destroy the souls that he has made. Or, like some of you, he might have said, O! it is a long time yet; it will be time enough to turn to God a year before the flood comes. But, no; "Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house."
Now, brethren, if you would be like Noah, you should be moved with fear. God has warned you, not once, nor twice, but a hundred times. God warns you in the Bible that "his wrath is revealed from heaven against all ungodliness and unrighteousness of men" - Romans 1:18. It says, "Except ye be converted ... ye shall not enter the kingdom of God" - Matthew 18:3; it says, that if you commit such things you shall die; it says that if you do not believe you shall be damned - Mark 16:16; it says that if you are not converted and become as little children, you shall not enter the kingdom of God - Matthew 18:3. Ah, then, man, have you ever trembled at the warning of God? No; then you are not like Noah; you are not like him, for he believed God. I tell you, you could not live on as you do, if you believe God's Word; it is because you are infidel at heart - that is the reason why you do not tremble at his Word: "By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house."
Again, you are warned by ministers. We are to receive the word at God's mouth, and warn the people; and if we do not warn you, God says he will require it at the watchman's hands. This is one of the chief parts of a minister's duty - to warn the unconverted. This is what I have done, both in public and in private. I have warned you, and how have you received it? O, you say, do you think I would be afraid of the word of a man? Well, if so, I tell you that it is not our word, it is the Word of God; and, oh! if you do not take the Word of God, spoken through the minister, you are not like Noah.
Again, you are warned by providence. Some of you have seen souls cut down, and yet you are left. Some of you have seen those whom you led into sin taken away, and yet you are left. Ah, brethren, can you say that you have not been warned? and how have you taken it? Some of you have gone deeper into sin. Ah! you are not like Noah. But some of you will make this objection. I do not like to be moved with fear; I like it to be all love. It is quite true that none were ever brought to Christ by fear. We must be brought to Christ by a sight of his love. But then, it is quite as true that you will never be brought out of your security but by fear: you must be drawn out by fear, and drawn in by love.
