Healing and Deliverance happens as God wills it. When you think it’s the man and woman of God who heals sicknesses, delivers from demon or perform miracles and wonders, you’ll call them powerful. Psalm 115:3 Our God is in heaven; he does whatever pleases him.
Everything happens according to his will and time. Paul, highly anointed in miracles and wonders left Tophimus sick. 2 Timothy 4:20 Erastus stayed in Corinth, but Trophimus I have left in Miletus sick. To everything you do, be led by the Spirit else younwill do things to entertain people and grieve the Spirit.
God does not do things because we want it to happen. Exodus 33:19 The LORD replied, “I will make all my goodness pass before you, and I will call out my name, Yahweh, before you. For I will show mercy to anyone I choose, and I will show compassion to anyone I choose.
