What is necessary to remember is that when you are introducing someone to the Lord Jesus Christ, you are presenting one that is a complete stranger to them, or at best is one to whom they have little knowledge of, and most of that knowledge will be incorrect.
Their misconceptions are of a truth their own fault, for Romans 1:20 is a truth. “For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:” Yet those invisible things, while they will lead one to Christ, do not speak of His sacrifice, they do not in themselves offer the truth of the price that was paid for them, their need of repentance and acceptance of the vile condition they are now in.
“But in vain they do worship me, teaching for doctrines the commandments of men.” (Matt. 15:9)
Those you will speak to have at best a rudimentary knowledge of the Savior, they may have heard John 3:16, but not the reason of a need for a perfect sacrifice, they may have some semblance of knowledge of the cross, but not the reason that the blood that was shed on it is necessary as the only covering accepted for their sins. They have heard the word “sin,” but have no concept of the word “holy.”
It is common for most to have at least stepped into what can loosely be called a church once in their life, heard perhaps a sermon and even for a short time contemplated the words spoken, but the general consensus of most people is that they are, or have been, good enough, that although there have been times that they have not lived up to what they consider God’s standards, for the most part, they have behaved in a manner that does not justify damnation.
The balance of the scales they believe will fall to their favor.
“For all have sinned, and come short of the glory of God;” (Romans 3:23)
It is quite disturbing to me to hear a preacher or other man of God say to this person, “If the Lord says to you at the gates of heaven, why should I let you into my Kingdom….” For that has never and never will happen, if you are at the gate, you are going in, no one who dies in their sins will ever even see those gates.
You must tell them the reason for the cross, love, and you must inform them of the consequences of refusing that love, eternal wrath.
From the rebellion of Adam to the daily sacrifices and their inability to remove sin, the revealing of the Son of God and His acceptable and perfect sacrifice for all who will believe on His name. “And almost all things are by the law purged with blood; and without shedding of blood is no remission.” (Heb. 9:22)
The complete and absolute Sovereignty of the Living God, the humility of dust, the offering of love, and the consequences of rejecting that love.
Many you will meet will need to be reproved and corrected, for they may have spent decades in a works-based religious cult, some may have at best a rudimentary knowledge of the Scriptures, but still believe in those scales of good and bad. Others will know next to nothing of the Lord Jesus Christ, to them He is a complete stranger.
Can you introduce Him to them? Do you know the Savior well enough, have you studied the Scriptures searching for Him, seeking out the face of God so that you can speak of the One you call Lord and Master?
He whom you say you serve; do you know Him personally enough to introduce Him to those you meet?
