Presenting the Gospel
How do you tell people that they need Jesus? Do you tell them that Jesus loves them and that He wants to make their lives better? Do you tell people that Jesus can forgive them of their sins? Do you tell them that Jesus has a wonderful plan for their lives and that they should believe in Him and ask Jesus into their hearts? If so, you may be doing a harm to their spiritual health. That's right, harm. Let me explain.
The Gospel
Because of the harshness and truth of the Law, we are broken before God and recognize that we can do nothing to please Him because we cannot keep the Law of God perfectly: "For all of us have become like one who is unclean, and all our righteous deeds are like a filthy garment..." (Isaiah 64:6). Therefore, the only thing left is to is come to the cross. This is why it says in Gal. 3:24, "Therefore the Law has become our tutor to lead us to Christ, that we may be justified by faith." The Law pushes us towards Jesus. It compels us to come to the only one who can forgive us of our sins. It breaks us so that we are found hopeless inside and we then turn to another to deliver us from the wrath of God. This is why Jesus came. This is what the gospel is about. Jesus died on the cross to avert the wrath of God from sinners. Therefore, the only way to be "saved" from the wrath of God, is to trust in Christ. This is what it means to be saved. It means to be saved from God's wrath: "Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him, (Rom. 5:9). The gospel is not about a "nice" God who is begging people to come to Him because He loves the sinner but hates the sin. (The Bible never says that God loves the sinner but hates the sin.) On the contrary: "The boastful shall not stand before Thine eyes; Thou dost hate all who do iniquity," (Psalm 5:5). And, "There are six things which the Lord hates, yes, seven which are an abomination to Him: 17 Haughty eyes, a lying tongue, and hands that shed innocent blood, 18 A heart that devises wicked plans, feet that run rapidly to evil, 19 A false witness who utters lies, and one who spreads strife among brothers," (Prov. 6:16-19). Such biblical teaching is not in harmony with most popular Christian theology today because it doesn't present God as the "nice" God that is begging people to come to Him. Instead, the truth is that God is Holy and He will punish the sinner. But that isn't all of it. God is also love (1 John 4:8) which is why He sent His Son, to save us: “For God did not send the Son into the world to judge the world, but that the world should be saved through Him," (John 3:17).
So, when you present the gospel to someone, make sure you preach the Law of God first. Let that Law work on the person you speak to. Let it break the heart open so the seeds of the gospel can take root. Let the Law of God make the sinner aware that He has sinned against God and that there is a coming judgment because of it. Then, when he is ready, tell him that "God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life," (John 3:16). Tell him about how Jesus who is God in flesh (John 1:1,14) was able to live the Law perfectly (1 Pet. 2:22), satisfy the Father in heaven (1 John 2:2), give to us His very righteousness, (Phil. 3:9), and deliver us from the Judgment to come (Rom. 14:10; Heb. 9:27). And when you do so, do it with grace: "Conduct yourselves with wisdom toward outsiders, making the most of the opportunity. 6 Let your speech always be with grace, seasoned, as it were, with salt, so that you may know how you should respond to each person," (Col. 4:5-6).
