God can do things that are contrary to what we consider His natural laws. When someone is healed of an incurable disease, for example, we call it a miracle because we’re seeing the evidence or manifestation of some of God’s laws that link the spiritual and the physical realms—laws that we know little about.
To God, on the other hand, it’s simple! He knows how to undo whatever damage the disease may have done and thereby creates what to us is a miracle, a supernatural act that is beyond our capabilities.
God is always ready, willing, and able to work miracles on our behalf, miracles of healing, supply, protection, or whatever else we may need when we ask Him to in faith and claim the promises from His Word.
Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father.
