Many people say there is no such thing as a loving God because evil exists. They say things like, "If there was a loving God, why would he let all of these terrible things happen?"
But by asking questions like that, aren't they really conceding that certain acts are evil? And when they say that there is evil, aren't they making a moral judgment? And if so, doesn't that also show they have a standard of good against which acts can be deemed evil? After all if there is no standard of good against which to judge, then there cannot be any judgment of wrong or evil.
And so we can see that such people effectively agree that there is a standard of both good and evil in the world, and that such judgments are based on morals.
But where do those morals come from? If everything comes from random chance over time and there is nothing objective, then we cannot have an objective standard to say that there is evil in the world. Yet because we ask why there is evil, we must accept there is a standard against which we judge.
That standard came from God. He wrote His law, the standard of good and evil, on each of our hearts. That standard of good and evil is also called the 10 commandments.
When we break one of these moral laws we feel uncomfortable. That's because we all know it is morally wrong to steal, murder and commit adultery; yet we break moral laws and deny our wrongdoing anyway. Why?
The Bible tells us why. It says that we "suppress the truth in unrighteousness". That means we know there is a God and we know that we will have to give an account when we stand before him (after we die).
So what happens when we stand before God? To answer that, we have to understand a bit about God's character.
First, God is holy (uncorruptable). Second, He is just. Third, He is all-knowing. Combine those characteristifcs, and when we honestly think about standing before him to be judged for all the things we've done in life, we have to at least be worried; and if we have even more understanding of how high His standard off good is, we should be completely terriried. God is just and we will have to give an account for each of our thoughts words and deeds. And He will have no choice but to punish wrongdoing (or He'd be a corruptable judge).
But fortunately for us, God is also merciful. So rather than have us pay the penalty for our sins, He sent his only Son Jesus to live a perfect life and die on the cross in our place. Unfortunately that meant Jesus had to die (because the Bible says the wages of sin is death).
Yet Jesus didn't sin. Thus God was still just in having Jesus rise from the grave 3 days later. And in doing so, God completely satisified His judegment, sentencing, and His supreme ethic of love by loving us so much that He paid the penalty of death for sins we committed. It's the greatest gift of grace, mercy and love ever shown.
That's why we must repent and trust that Jesus did this for us. Receive God’s mercy now! Repent and trust in Jesus!
