It shows the intervention of a power that is not limited by the laws either of matter or of mind, a power interrupting the fixed laws which govern their movements, a supernatural power. The suspension or violation of the laws of nature involved in miracles is nothing more than is constantly taking place around us. When a man raises a weight from the ground, the law of gravity is neither suspended nor violated, but counteracted by a stronger force. The same is true as to the walking of Christ on the water and the swimming of iron at the command of the prophet. Thus we affirm the possibility of miracles, the possibility of a higher hand intervening to control or reverse nature's ordinary movements.
Miracles are seals of a divine mission.
The sacred writers appealed to them as proofs that they were messengers of God. Thus, being out of the common course of nature and beyond the power of man, they are fitted to convey the impression of the presence and power of God. Where miracles are there certainly God is. The teacher points to these credentials, and they are a proof that he speaks with the authority of God. The credibility of miracles is established by the evidence of the senses on the part of those who are witnesses of them, and to all others by the testimony of such witnesses.
