We are all born with a sense of right and wrong. Before children can even speak, they have a sense of it. You can tell by watching them. They check to see if they can get away with something, and when you tell them no, they do it anyway.
Right and wrong are in our human nature. There is a human conscience. Romans 1:18 says, "God shows his anger from Heaven against all sinful, wicked people who suppress the truth by their wickedness."
Some say they live by their own standards, but I would argue they don't. They know what is right, and they know what is wrong. And they have broken their own human standards. We are told in Romans 2:12, "When the Gentiles sin, they will be destroyed, even though they never had God's written law. And the Jews, who do have God's law, will be judged by that law when they fail to obey it."
Down in our hearts, we know right from wrong. God's laws are written within them. Our own conscience either accuses or excuses us. And God will judge us according to the light we have received.
Know this: God wants to save us even more than we want to be saved. Jesus said, "For the Son of Man came to seek and save those who are lost" (Luke 19:10).
David told his son Solomon, "Learn to know the God of your ancestors intimately. Worship and serve him with your whole heart and a willing mind. For the Lord sees every heart and knows every plan and thought. If you seek him, you will find him. But if you forsake him, he will reject you forever" (1 Chronicles 28:9).
If you are a true seeker, then you will find your way to Jesus Christ.
