“He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before My Father and before His angels.”
In His messages to each of the seven churches in Revelation 2 and 3, Jesus Christ listed the blessings that He will give to those who overcome. To overcome is to endure in obeying God in spite of trials and temptations and persecution. Overcoming means using God’s help to become victorious over sin and Satan’s way.
The Book of Life is God’s record of those to whom He will give the gift of eternal life in His Kingdom. This is the awesome promise God has set before those He has called if they overcome and remain faithful till death.
“To not blot out is a figure of speech, affirming a positive by negating its opposite. Thus it means, ‘I will include their names.’ Blot out likely alludes to Ex. 32:32, 33, where God says He will blot out sinners, but not faithful ones like Moses, from His Book” (NKJV Study Bible, note on Revelation 3:5).
What a wonderful promise, to have Jesus Christ announce the overcomers’ names before God!
