The adult explanation would be…
http://www.christiananswers.net/dictionary/miracle.html calls it “an occurrence at once above nature and above man. 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. One force counteracts another: vital force keeps the chemical laws of matter in abeyance; and muscular force can control the action of physical force.
Show the children the following – When a man raises a weight from the ground, the law of gravity is neither suspended nor violated, but gravity and the weight is counteracted by a stronger force, the strength of the man.
Tell them – The same is true as to the walking of Christ on the water.
God was there overcoming the power of gravity to cause Christ to sink by His miraculous power to keep Him afloat. That was a miracle.
Now that we know what a miracle is, we are going to study many of these biblical miracles to see why God intervened with His power.
