He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him. – John 3:36

Because I live, ye shall live also. – John 14:19

Blessed is that man who hath everlasting life, who is made a partaker of the divine nature, who is born again from above, who is born of God by a seed which remaineth in him; for he is the man upon whom the second death hath no power, who shall enjoy life eternal when the wicked go away into everlasting punishment.

We have now to ask each of you whether you have received it. Have you been born, not of blood, nor of the will of the flesh, nor of the will of man, but of God? Was there a time with you when you passed from death unto life, or are you abiding in death? Have you the witness in yourself that you have been operated upon by a divinely spiritual power? Is there something in you which was not once there, not a faculty developed by education, but a life implanted by God Himself? Do you feel an inward craving unknown to carnal minds, a longing desire which this world could neither excite nor gratify? Is there a strange sighing for a land as yet unseen, of which it is a native, and for which it yearns? Do you walk among the sons of men as a being of another race, not of the world, even as Christ was not of the world? Can you say, with the favoured apostle, “We know that the Son of God is come, and hath given us an understanding, that we may know Him that is true, and we are in Him that is true, even in His Son Jesus Christ. This is the true God, and eternal life.” Oh! then, thank God for this, and thank God yet more that you have an infallible guarantee for this, and thank God yet more that you have an infallible guarantee that your life shall be continued and perfected, for so saith the text, “Because I live, ye shall live also.” ~ C.H. Spurgeon
