There's a song by the Gaithers called "When the roll is called up yonder" and the next line is "I'll be there."
Speaking of New Jerusalem:
"Its gates shall not be shut at all by day (there shall be no night there). And they shall bring the glory and the honor of the nations into it. But there shall by no means enter it anything that defiles, or causes an abomination or a lie, but only those who are written in the Lamb’s Book of Life."
The roll call from Jesus reminded me of several scriptures I love very dearly. The illustrate the moment when certain of God's prophets were called. They heard God, and they responded "Here I am!" They report for the highest duty possible, a life of total dedication and obedience to Jesus. This is the only proper response to His call. It moves me to think of them saying "Here I am!" to God. These are the men whom God called:
Abraham, when God tested his faith: - Genesis 22:1, 11,
Jacob, in a dream, hears the LORD say that He sees Jacob's ill treatment by Laban - Genesis 31:11
Moses, seeing the burning bush and hearing the Angel of the Lord call Moses to perform the Exodus - Exodus 3:4
Samuel, as a boy, receiving his first call from the LORD. - 1 Samuel 3:4
Isaiah, in a vision from Isaiah 6:8, receiving his call to Prophet after seeing the LORD on His throne and exclaiming he is a man of unclean lips, being cleaned with the live coal, then eagerly answering God, "Here I am, send me!"
"Here I am!" they all said.
Now get this. Picture in your mind the great multitudes that appear before Jesus in heaven after the rapture. You are wearing a white robe and are enjoying a glorified body. You are seeing things unparalleled and experiencing indescribable joy. You see Jesus' face, and you can't get enough. In the midst of this, imagine Him opening the Lamb's Book of Life, in which your name is written. And 'books were opened' and the roll is called...and then then He calls your name.
Because of His sacrifice, because of His love, because of the blood, because you repented, you will say:
HERE I AM!
