The Bible is full of examples of open air preaching and it wasn't that long ago in our land before the distraction of the television and other media outlets that it was a common sight. People would gather to hear the Word of God. The need is still the same. Man is still a sinner, the wages of sin is still death eternal, and people need to repent of their sins and believe on the gospel of the Lord Jesus Christ.
False religion and the liberal media are busy spreading their lies. How can we honor our Lord if they are more busy spreading their damnable lies than we are busy spreading the truth of the gospel?
How can we expect God to save sinners when we don't share the gospel of Christ? Romans 1:16 says that the gospel is the power of God unto salvation.
Some may say that it won't yield results. First, God said to do it. Second, what kind of results are we looking for? Third, tell that to Jeremiah, Noah, and many others who preached in obedience to God for the glory of God.
We simply must sow the seed of the gospel, water it with prayers, tears and more preaching, and realize God must give the increase. If we try to give the increase, we make people twofold more the child of hell, wolves in sheep's clothing, reproaching the Name of Christ, in making them simply religious.
God help us to be faithful to the end. With our freedoms eroding day by day, we may only enjoy the kind of freedom we have now to open air preach for just a short time.
The Word being preached can be God's means to bring about revival, to save sinners, to restore our land to more what it used to be with more righteousness that exalted this nation in years gone by.
Luke 10:2 Therefore said he unto them, The harvest truly [is] great, but the labourers [are] few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.
Here is some open air preaching that we try to do at least once a week in different places as are led of the Holy Spirit:
