Why should I repent? Because there is appointed a day for each person to die and then comes the judgment of God and you have sinned against Him. You have broken His laws. Now you might say, "Wait a minute. I'm a good person. I've never done anything so bad as to deserve to go to hell!"
Well, let's just look into that claim shall we?
I would like to challenge you to ask yourself some tough questions to see if you are really a "good" person. Answer these questions in your own heart and mind and be honest with yourself.
How many lies have you told in your lifetime? Have you told too many to count? Or perhaps told just a few lies? It doesn't matter if they were little white lies or not if you were doing it with the intention to deceive another or protect yourself it's still a lie. And it doesn't matter if "everybody lies" that does not change God's standard. Lying lips are an abomination before the Lord. Just as it only takes the murder of one individual to be considered a murderer it takes only one lie to be considered a liar and all liars will have their place in the lake of fire.
I've heard it before some of you are saying "wow, that's pretty heavy handed of God to send someone to hell for telling one lie. But consider this. If I lie to my kid what will happen? He might be mad at me for a while, right? If I lie to my wife, I'm sleeping on the couch. If I lie to a judge in a court of law that's perjury and I can go to jail. If I lie to the government that's treason and I could lose my life. What is the same about all of these examples? I lied. The difference is the authority to which the offense was committed and therefore the punishment is different. God is the ultimate authority and when we lie it is offensive to Him. Remember God is holy, just and righteous.
Have you ever taken anything that wasn't yours no matter how small? Perhaps, you downloaded music you never paid for but should have or you cheated on a test and thereby stole answers. If you have that makes you a thief and according to God's word no thief will inherit the kingdom of heaven. (1Cor 6:9-10)
Have you ever taken God's name in vain, used it irreverently or carelessly. If you have that is called blasphemy and the Lord will not hold him guiltless who blasphemes His name.
Jesus said you have been told do not commit adultery but I tell you if you look at a women to lust after her you have committed adultery with her already in your heart. Have you ever looked at someone with lust or sexual desire? Then you are an adulterer at heart and no adulterer will inherit the kingdom of heaven.
If you are like most people and are guilty of each one of these then know this, God sees you as a liar, a thief, a blasphemer and an adulterer at heart. So you are not a good person. You are just like the rest of us guilty of breaking God's law and it is because you are guilty and that God is good and just that He must send you to hell. God will not allow sin to enter heaven and that includes you!
Now after this you might be thinking "By God's standard no one deserves to go to heaven and we all deserve to go to hell" and you would be right. Who then can be saved from the wrath of God? The apostles asked this question of Jesus and He said, "by man this is impossible but by God nothing is impossible". Jesus is saying that you cannot save yourself only God can save you!
How can God save me? God condescended and took on human form in the man Christ Jesus. He was fully man and fully God at the same time. Jesus willingly laid down His life and became the final sacrifice for sin. The wrath of God that you and I so richly deserve was poured out on His only Son so that if we will rightly respond to the gospel, the good news, that Jesus died for our sins we may have eternal life.
How then can I be saved? You can only be saved by an act of God. I would love to tell you "just say the sinners prayer" or "walk an isle" but the fact is you are helpless.
The better question might be this: While reading this and asking yourself these questions has God so moved on your heart that you now hate the sin you once loved? If God has brought you to an end of yourself and you are done leading your life your way then perhaps you are ready to repent and believe.
