1 John 3:16 (ESV)
By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers.
Here is a great story illustrating What God did for us.
After a few of the usual Sunday evening hymns, the church's pastor slowly stood up, walked over to the pulpit and, before he gave his sermon for the evening, briefly introduced a guest minister who was in the service that evening. In the introduction, the pastor told the congregation that the guest minister was one of his dearest childhood friends and that he wanted him to have a few moments to greet the church and share whatever he felt would be appropriate for the service.
With that, an elderly man stepped up to the pulpit and began to speak. "A father, his son, and a friend of his son were sailing off the Pacific Coast," he began, "when a fast approaching storm blocked any attempt to get back to shore. The waves were so high that, even though the father was an experienced sailor, he could not keep the boat upright, and the three were swept into the ocean as the boat capsized."
The old man hesitated for a moment, making eye contact with two teenagers who were, for the first time since the service began, looking somewhat interested in the story. The aged minister continued with his story. "Grabbing a rescue line, the father had to make the most excruciating decision of his life: to which boy he would throw the other end of the life line. He only had seconds to make the decision. The father knew that his son was a Christian, and he also knew that his son's friend was not. The agony of his decision could not be matched by the torrent of the waves. As the father yelled out, 'I love you, son!', he threw out the life line to the son's friend. By the time the father had pulled the friend back to the capsized boat, his son had disappeared beneath the raging swells into the black of night. His body was never recovered."
By this time, the two teenagers were sitting up straight in the pew, anxiously waiting for the next words to come out of the old minister's mouth. "The father," he continued, "knew his son would step into eternity with Jesus, and he could not bear the thought of his son's friend stepping into an eternity without Jesus. Therefore, he sacrificed his son to save the son's friend. How great is the love of God that He could do the same for us. Our heavenly Father sacrificed His only begotten Son that we could be saved. I urge you to accept His offer to rescue you and take hold of the life line."
With that, the old man turned and sat back down in his chair as silence filled the room. The pastor again walked slowly to the pulpit and delivered a brief sermon with an invitation at the end. However, no one responded to the appeal. Within minutes after the service, the two teenagers were at the old man's side. "That was a nice story," politely said one of the boys, "but I don't think it was very realistic for a father to give up his only son's life in hopes that the other boy would become a Christian."
"Well, you've got a point there," the old man replied, glancing down at his worn Bible. Sorrow began to overtake the old man's smiling face as he once again looked up at the boys and said, "It sure isn't very realistic, is it? But I'm here today to tell you that I understand more than most the pain God must have felt to give up His only Son. For you see, I'm the man who lost his son to the ocean that day, and my son's friend that I chose to save is your pastor."
Dear Lord, help our hearts and minds be set on sharing Your love with those you bring into our life. In the Name of Jesus, Amen.
