“5 He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.” (Rev 3:5)
The white raiment means we get to wear the garment of Christ’s righteousness. Our names are in the book of life, meaning we have a paid in full ticket to spend an eternity in Heaven with our Lord. Jesus will speak up for us so that we can be with Him.
