One evening, while I was working outside in my yard, my neighbor came over. We weren’t really friends, but we had always spoken whenever we saw each other. Once, when my car wouldn’t start, he offered to drop me at the office. That night, though, he invited my wife and me to his church the following Sunday. His pastor had just begun speaking on what the Bible said about being an influential man. I wanted to be a man of influence. As the pastor spoke that morning, I knew that the influence and success I had achieved could never be enough. I understood that I was a sinner and could never pay the price of being “good enough” to deserve heaven. The only thing that really mattered was Jesus Christ and His death on the cross for MY sin. When he gave the invitation for us to accept Jesus Christ as our Savior, I knew that I needed to be saved, to accept Jesus and that His work was sufficient to assure me of God’s love for me and a place in heaven. I realized it was not enough to just know about Jesus, but that I needed to know Him, personally. I did accept Jesus Christ that Sunday and placed all of my faith in Him and His work on the cross and was baptized. I will always be grateful to my neighbor who invited me to attend church with him.
