To those that overcome, they will be given the tree of life  -  Revelation 2:7

He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.

The Spirit of God told of the promise that could be given to the overcomer. An overcomer, according to John, is one who believes that Jesus is the Son of God. One who believes that is a true believer, and their faith enables them to overcome the world with all of its temptation and allurements. The blessings of being an overcomer – we will enjoy all of the blessings of the fullness of eternal life.
