I have read the Bible for some 50+ years now and have found no scriptures instructing the average lay Christian to either preach to sinners or to attempt to save any sinner's soul. If you have discovered such scripture, please post it. Thank you in advance.
Matthew 28:19-20King James Version (KJV)
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Mark 16:15-16English Standard Version (ESV)
15 And he said to them, “Go into all the world and proclaim the gospel to the whole creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
Thank you again. I am well aware of both these scriptures, however, these instructions were specifically given by the Christ to the Apostles and not to any lay Christian.
For the record I am not a Bible believing Christian. I am convinced that if there is a judging God He will not judge us by what we believe but rather how we live our lives in accordance with those beliefs. However, I have studied the Bible for over 60 years and have many Christian friends. . When Christians spread the word they are living their faith and that is a wonderful thing . One of my best friends is a Christian and he told me Christians who don't spread the word are either spiritually lazy or they are ashamed to openly declare their faith.
Then your friend is making a judgment of other Christians himself is he not? You see, he too is biased.
I have never been offended or harmed in any way by Christians who wanted to share their faith. When the Jehovah's Witnesses come to the door I tell them I would be glad to discuss the Bible with them, but I caution them that I am steadfast in my own faith and would not change. Once the parameters are set conversations are short but friendly.
If Christians feel they have found the truth and their lives have been enriched thereby, there is nothing wrong with them sharing their experiences and spreading their joy. And if they are genuinely convinced that those who did not believe in Christ were going to hell, I would expect them to do everything in their power to prevent this from happening; hell, I'd be preaching from the rooftops.
Christians should be guided by what the Bible says and there is a scriptural basis for proselytizing. Here are a few of the relevant verses:
“Son of man, I have made thee a watchman unto the house of Israel: therefore hear the word at my mouth, and give them warning from me. When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand. Yet if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul” (Ezekiel 3:17-19, KJV).
This mandate to warn sinners of their wicked ways applies to all people, not just apostles. Although these Old Testament words do not address the Christian faith directly, it is nonetheless applicable to Christianity since it applies to each and all. The most direct references to a duty to publicly declare Christ come for the New Testament in verses such as the following (these verses clearly apply to ALL Christians, not just apostles):
“Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven” (Matthew 10:32; see also Luke 12:8, Romans 10:9, and 1 John 4:15, KJV).
“Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels” (Mark 8:38, KJV).
People have different ways of doing almost everything and when it comes to spreading the Word some Christians are more personable than others. During my long life, I have encountered both the rudely aggressive and the friendly persuader. Even on the Internet you can see the various styles of those Christians on a conversion mission. Some belittle and degrade, while others are positive and caring. It is what it is. I suggest that when you criticize Christians for their attempts to convert you, it is proper to condemn their methods, but not their goals.
Conclusion: There are specific verses in the Bible which require Christians to proselytize. However, even in the absence of such specificity Christians would still have a duty to share the Word just as they would share other good things in their life. This is nothing more than common courtesy and caring. Besides, to a Bible believing Christian sharing the Word is more than just spreading good news; it is literally a matter of life or death. The Biblical message is that only those who accept Christ will be saved, and common sense dictates that only those who hear of Christ could possibly accept Him. Why would anyone expect Christians to remain silent when there is so much on the line?
