Your host is the Lord God Almighty. The banquet is for His Son. Below is an easy way to accept His invitation.
All you have to do is admit that He exists, admit that you can not get to the banquet without His help, acknowledge that He has provided a way for you to reach Him and attend the banquet for His Son.
You can do all these things by saying these words to Him:
Lord, I admit that You created all things, and that I have not met the requirements You explained in Your instruction book, the Holy Bible, for fellowship and life with You.
I acknowledge that You gave me a second chance for eternal life with You through Your only begotten Son, Jesus Christ, and that You sent Him to me to remove the barriers that separate us. Your Son did that by willingly accepting the punishment for the wrongs I have done. He was put to death for the wrong I have done. You raised Him from the grave, brought Him to heaven, and He reigns at Your right hand. I accept your Son, Jesus Christ, as my Lord and Savior. Amen.
Congratulations! You have reserved your seat at the banquet of our Lord and Savior, Jesus Christ, and can enjoy eternal life and fellowship with Him.
