After I preached with the sketchboard on the subject of "The way to Heaven", I noticed there were two young men who had been listening for almost the entire time that I preached and they were still hanging around afterwards.
So I went up to one of them, his name was David. He said he was a Mormon. When I asked him how he thinks he will get to Heaven, he said he was hoping that following the Mormon process of repentance would save him - getting baptised, confession to the bishop, asking for forgiveness, trying to do better, etc.
I pointed him to Matthew 5:48 where Jesus said you must be perfect. That means trying to do better will not undo the sins he has done before. Nor will merely asking for forgiveness get rid of his sins because God is just and will by no means clear the guilty.
He was beginning to understand that and asked what he can do then to be saved. So I pointed him to the cross, that the way to Heaven is only by having a perfect person take our Hell punishment for us on our behalf, that is Jesus. He replied, "But I already believe Jesus died on the cross."
I said, "Yes, but you're not trusting only in His death on the cross for your forgiveness. You think it is Jesus plus your good works." David realised that and as I explained it further, he was coming to understand the gospel. But he also realised his family wouldn't let him leave Mormonism to trust only in Jesus.
So I asked him, "What is more important, pleasing God or pleasing your family?" He replied, "Pleasing God." Please pray for David that he will take the bold step of leaving Mormonism to trust only in Jesus for his forgiveness.
To God be the glory!
