Jesus not only demands your trust, He deserves it. You need healing; He came to heal those who need healing. He can heal you. What are you to do in order that you may be healed? What are you to do in order that all your sins may be forgiven and yourself saved? All of this is to be done by Jesus. According to Charles H. Spurgeon:
When [Jesus] tells you that if you trust [Him] you shall find peace, [and] you tell him it is not possible there can be any peace to you; when he reminds you that he never rejected one, you insinuate that he will reject you; you thus insult the Divine Majesty by denying the truthfulness and honesty of God. You do need healing when you allow wicked despair to get the mastery of you like this; you are far gone, very far gone, but I rejoice to know that you are still among those Jesus is able to heal. He came to those who needed healing, and you cannot deny you are one of those. Why, even Satan himself will not have the impudence to tell you that you have no need of healing. Oh, if only you would cast yourself into the Savior’s arms – not trying to make yourself out to be good, but acknowledging all that I have laid to your charge, and then, trusting as a sinner to that Lamb of God that takes away the sin of the world.
Remember you need healing, for unless you are healed of these sins, and of all these wicked tendencies and thoughts, as sure as you are a living man you will be cast into hell. I know of no truth that ever causes me such pain to preach as this, not that sinners will be damned, awful though the truth of that is, but that awakened sinners will be damned unless they believe in Jesus. You must not make a Christ out of your tears; you must not hope to find safety in your bitter thoughts and cruel despairs. Unless you believe you shall never be established. Unless you come to Christ, you may be convinced of sin, of righteousness and judgment too, but those convictions will only be preludes to your destruction. You call yourself a seeker, but until you are a finder you are an enemy to God, and God is angry with you every day. I have no alternative for you, however tender and broken-hearted you may be, but this one – believe and live; refuse to believe, and you must perish, for your broken-heartedness, and tears, and professed contrition can never stand in the place of Christ. You must have faith in Jesus, or you must die eternally.
I need not enter into what your case is. Remember, Jesus has saved a parallel case to yours. Yours may seem to yourself to be exceedingly odd, but somewhere or other in the New Testament you will find one as singular as yours. You tell me that you are full of so much wickedness. Did he not cast seven devils out of Mary Magdalen? Yes, but your wickedness seems to be greater than even seven devils. Did he not drive a whole legion of devils out of the demoniac of Gadara? You tell me that you cannot pray, but he healed one possessed of a dumb devil; you feel hardened and insensible, but he cast out a deaf devil. You tell me you cannot believe; neither could the man with the withered arm stretch it out, but he did it when Jesus ordered him to. You tell me you are dead in sin, but Jesus made even the dead live. Your case cannot be so bad that it has not been matched, and Christ has conquered. . . . (Advice for Seekers)
