Answer: First let us take a look at the verse in question. Revelation 3:5 says, [italics] 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.
Before judging what a verse means, we must consider the context in which it was written by reading the surrounding verses or chapters. In this case, Christ is addressing the seven apocalyptic churches. Christ was speaking both to saved and unsaved individuals within the church. In this passage, each church was given a different reward for overcoming.
So what does the term “overcomer” mean for us as believers today? 1 John 5:4–5 explains, For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
This passage proves that overcoming is putting our faith in Jesus Christ. To overcome is not to persevere to the end or to have victory over our besetting sins. If we have accepted Christ’s salvation, we are overcomers and are guaranteed an eternity in Heaven with our Savior.
