Those that come unto Jesus are His chosen people. These people's hearts are open and they have an ear to hear God's truth.
Jesus is the only way to heaven. Believe in and follow Him and you shall be saved. The truth and the life is in Him.
John 14:5,6 (KJV)
5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
