The Holy Spirit guided Noah in his preaching. God has always given the message to be preached unto His messengers. Today, we have it in an inspired book. Then, they had it in an inspired man. In order for Noah to have something to preach, God must have given it to him. Second Peter 2:5 says, “And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly.” Noah was God’s preacher of righteousness in that world of unrighteousness. Yet, in Genesis 6:3 we read, “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.” God says that during this time, His Spirit was striving with man. How was He doing that? I submit to you that God’s Spirit was striving with man through the preaching of Noah.
Was it not with Noah as it was with God’s people during the wilderness wandering? Of that period of time Nehemiah 9:20 records, “Thou gavest also thy good spirit to instruct them, and withheldest not thy manna from their mouth, and gavest them water for their thirst.” Later, Nehemiah 9:30 says, “Yet many years didst thou forbear them, and testifiedst against them by thy spirit in thy prophets: yet would they not give ear: therefore gavest thou them into the hand of the people of the lands.” God in His longsuffering strove with His people in the land of Cannan. How did God do this? He testified against them BY His Spirit IN his prophets! So it was in the days of Noah.
The longsuffering of God waited during the days of Noah for some 120 years (Gen 6:3; 1 Pet. 3:21). During this period of time God strove with the people by His Holy Spirit in Noah the preacher. Obviously, the Holy Spirit guided Noah in his preaching.
Was it not with Noah as it was with the other preachers and prophets of God? Peter wrote, “For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost” (2 Pet. 1:21).
One final thought,…can we not say that God’s Spirit is striving with man today? Certainly so! The Holy Spirit is using His sword (which is the word of God, Eph. 4:11) to lead us to repentance. “For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart” (Heb. 4:12). As God’s people use the word of God to convict the hearts of others, God strives with them. In His longsuffering, Christ has not yet come. But one day, those days of longsuffering will end just as they did in the days of Noah. Peter writes, “For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: Whereby the world that then was, being overflowed with water, perished: But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men…The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness” (2 Pet. 3:5ff).
