What is of utmost importance? The number one job of the Christian and the last command of the Savior? But the proclamation of the Gospel of Jesus Christ to the lost. Not all who preach the Gospel will do it for a good reason.
As Paul said, some preach Christ out of rivalry or envy. What is important is that Christ is proclaimed as crucified. God will use it for the saving of souls because it is the Gospel that has the power to salvation, not the preacher.
Do not worry if you stumble or stammer as you share the Gospel. Learn from your mistakes and keep going. And do not try to stop others who you think are not doing it right. God can use them as well to bring the soul-saving power of the Gospel to the lost.
I have heard of Atheists preaching the Gospel and reading entire books of the Bible on video. Posting them online for others to watch. They thought they were ridiculing those who preach it and making fun of the Message of Christ. Yet, hundreds of thousands of Atheists and others are watching and hearing the Word of God! And many have come to Christ because they proclaimed it out of disdain.
So, I say if one is proclaiming Jesus and the Gospel for any reason, leave them be. Praise the Lord that the Gospel is being proclaimed by any means. They don’t even know that they are doing the will of God. In the Law, it is written: “Through men of strange tongues and through the lips of foreigners I will speak to this people,”
Keep doing the will of God in your life to share the Gospel of Jesus Christ. Step out in faith and speak up for Christ. Remember not to worry if you stumble or stammer or don’t think you are doing it right, preach Christ wherever you go anyway. Whether it is by your own words or by handing out Gospel Tracts. God says, “It shall not return to me empty, but it shall accomplish that which I purpose.”
I want you to know, brothers, that what has happened to me has really served to advance the gospel so that it has become known throughout the whole imperial guard and to all the rest that my imprisonment is for Christ. And most of the brothers, having become confident in the Lord by my imprisonment, are much more bold to speak the word without fear.
Some indeed preach Christ from envy and rivalry, but others from goodwill. The latter do it out of love, knowing that I am put here for the defense of the gospel. The former proclaim Christ out of selfish ambition, not sincerely but thinking to afflict me in my imprisonment. What then? Only that in every way, whether in pretense or in truth, Christ is proclaimed, and in that I rejoice. Yes, and I will rejoice, Philippians 1:12-18
