Cast all your anxiety on him because he cares for you. 1 Peter 5:7, NIV.
Grief, anxiety, discontent, remorse, guilt, distrust, all tend to break down the life forces and to invite decay and death (The Ministry of Healing, 241).
This feeling of guiltiness must be laid at the foot of the cross of Calvary. The sense of sinfulness has poisoned the springs of life and true happiness. Now Jesus says, Lay it all on Me; I will take your sin. I will give you peace. Destroy no longer your self-respect, for I have bought you with the price of My own blood. You are Mine; your weakened will I will strengthen; your remorse for sin I will remove.
Then turn your grateful heart, trembling with uncertainty, and lay hold upon the hope set before you. God accepts your broken, contrite heart. He offers you free pardon. He offers to adopt you into His family, with His grace to help your weakness, and the dear Jesus will lead you on step by step if you will only put your hand in His and let Him guide you.
Satan seeks to draw our minds away from the mighty Helper, to lead us to ponder over our degeneration of soul. But though Jesus sees the guilt of the past, He speaks pardon; and we should not dishonor Him by doubting His love....
If you feel yourself to be the greatest sinner, Christ is just what you need, the greatest Saviour. Lift up your head and look away from yourself, away from your sin, to the uplifted Saviour; away from the poisonous, venomous bite of the serpent to the Lamb of God who taketh away the sin of the world.
He has borne the burden of our guilt. He will take the load from our weary shoulders. He will give us rest. The burden of care and sorrow also He will bear. He invites us to cast all our care upon Him, for He carries us upon His heart (Mind, Character, and Personality 2:451, 452).
When the gospel is received in its purity and power, it is a cure for the maladies that originated in sin. The Sun of Righteousness arises, “with healing in his wings” (Malachi 4:2)....
The love which Christ diffuses through the whole being is a vitalizing power. Every vital part—the brain, the heart, the nerves—it touches with healing. By it the highest energies of the being are roused to activity. It frees the soul from the guilt and sorrow, the anxiety and care, that crush the life forces. With it come serenity and composure. It implants in the soul joy that nothing earthly can destroy—joy in the Holy Spirit—health-giving, life-giving joy (The Ministry of Healing, 115).
