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

“Ye shall live.” I think I see in that much more than lies upon the surface. Whatever is meant by living shall be ours. All the degree of life, which is secured in the covenant of grace, believers shall have. Moreover, all your new nature shall live, shall thoroughly live, shall eternally live. By this word it is secured that the eternal life implanted at regeneration shall never die out. As our Lord said so shall it be…”Ye shall live,” applies to all the parts of our new-born nature. If there be any believer here who has not lived to the full extent he might have done, let him lay hold upon this promise; and seeing that it secures the preservation of all his new nature, let him have courage to seek a higher degree of health. “I am come,” saith Christ, “that ye might have life, and have it more abundantly.” There is no reason, Christian, why your love to Jesus should not become flaming, ardent, conquering; for it lives, and ever must live…Here in your Lord’s promise the abiding nature of the vital faculties of your spirit is guaranteed. There is no stint in the fullness of Christian life. Beneath the skies I would labour to attain it, but herein is my joy, that it shall be most surely mine, for this word is faithful and true. As surely as I have this day eternal life by reason of faith in Christ Jesus, so surely shall I reach its fullness when Christ who is my life shall appear. Even here on earth I have the permit to seek for the fullest development of this life; nay I have a precept in this promise bidding me to seek after it. “Ye shall live,” means that the new life shall not be destroyed-no, not as to any of its essentials. All the members of the spiritual man shall be safe; we may say of it as of the Lord Himself, “Not a bone of Him shall be broken.” The shield of Christ’s own life covers all the faculties of our spiritual nature. We shall not enter into life halt or maimed; but He will present us faultless before the presence of His glory, not having spot or wrinkle, or any such thing, much less any dead limbs or decayed faculties. It is a grand promise and covers the spiritual nature as with the wings of God. Psalm 91:4 ~ C.H. Spurgeon
