Miracles, signs and wonders are important in building up our belief and faith in God, the almighty creator of Heaven and Earth. Things which can be explained can often be attributed to be natural. The awe and wonder at what God can do has a great impact in strengthening our belief in Jesus Christ and Father God.

God made man in His image.

Was this the outward appearance? OR Was it the inner being which is non-tangible was made like God? 

Faith is to believe what you do not see.
The reward of this faith is to see what you believe.
