Jesus said to her, “I am the resurrection and the life. He who believes in Me, though he may die, he shall live. And whoever lives and believes in Me shall never die. Do you believe this?” – John 11:25.26

For some of you, the time is late, very late; yet it is not too late. You are getting into years, my friend. I want you to believe that even now Christ can save you. I am glad to see the aged saints; but amongst so many elderly people, no doubt, there are some unsaved sinners, whose grey hairs are not a crown of glory, but a fool’s cap. But however old you are, though you are sixty, seventy, eighty or even ninety years of age, yet even now Christ can give you life. Blessed be God for that! But it is not altogether the years that trouble you; it is your sins. If you have gone to the very extremity of sin, you may believe that, after all those years of wandering, the arms of free grace are still open to receive you even now. There is an old proverb, “It is never too late to mend.” It is never too late for us to mend ourselves, but it is never too late for Christ to mend us. Christ can make us new, and it is never too late for Him to do it. If you come to Him, and trust Him, He will receive you even now.

By the longsuffering of God, there is a time left to you, in which you may turn to Him. What a thousand mercies it is that even now is a time of mercy to you: it might have been the moment of your everlasting doom! You have been in accidents; you have been within an inch of the grave many times; you have been ill, seriously ill; you have been well-nigh given up for dead; and here you are yet alive, but still an enemy to God! Plucked by His hand from the fire and flood, and, mayhap, from battle; delivered from fever and cholera, and still ungrateful, still rebelling, still spending the life that grace has lent you in resisting the love of God! …O God, strike many a man down, as Thou did Saul of Tarsus, and change their hearts by Thine own supreme love, as Thou canst do it, even now, on the very spot where they sit or stand. Amen. ~ C.H. Spurgeon
