If you are the tenth caller you'll win five tickets to the grateful dead concert. Now, put down that phone, there are no tickets, I am just remembering some of the ad copy I've written in my radio days. One thing you always wanted was a sense of urgency. You must act now was written in to every ad.
In John 7:33-34 we read: Then Jesus said to them, “I shall be with you a little while longer, and then I go to Him who sent Me. 34 You will seek Me and not find Me, and where I am you cannot come.” NKJV

The saying puzzled those who sent for Jesus. Why couldn't they go to where Jesus was going? It is because they lacked the one thing that would permit them entrance, faith! In Hebrews 4:2 it reads: For indeed the gospel was preached to us as well as to them; but the word which they heard did not profit them, not being mixed with faith in those who heard it. NKJV

Without faith it is impossible to please God. Even though the religious leaders were doing everything the law prescribed, they lacked the one thing the law could not provide, faith. Jesus told them where He was going and that they would not find Him because they could not come there. But, faith is the entrance into the eternal kingdom and if you believe and trust in God, then you shall enter and find that Christ, the Great I Am will come and dwell with you.

But you must act while you still have time. You only have this life to act on this opportunity, after this life, you will have no chance. And, your life is passing quickly, don't lose the opportunity to believe the gospel and receive Christ as Lord and Savior.
