James 1:15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
Note that ... sin, when it is finished, bringeth about death. And when is sin finished ? ... when it has completely estranged us from God. There is no question that we must endure ... in our walk with God, for this is the essence of our quest ... to be with God.
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.
... and how do we overcome ?Revelation 12:11 And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
