One of the main premises of Christianity is that Jesus is fully man and fully God. People seldom deny that Jesus was a man, yet his deity is often the point of controversy. Jesus was born to a woman, but he was conceived by the Holy Spirit, and his father is God. In his time among us, he did much to demonstrate that he is God the Son.
The first supernatural event that Jesus presented, when he was about to begin his ministry here on earth, was to turn water into wine (see John 2:1-11). He was at a wedding banquet, and the wine was running out. He ordered servants to fill 6 stone jars with water. Each jar held twenty to thirty gallons. When they were full, he instructed them to take some to the master of the banquet. The water had become fine wine.
Water is as you know H2O. Its elemental make up is two hydrogen and one oxygen atom. Wine is about 84% water, and 13% ethanol. The other 3% is a complex combination of glycerol, organic acids, amino acids, sugars, other alcohols, phenols, minerals, aromatics, and sulfur. Not only did Jesus turn water into wine, but he made the best wine.
Other supernatural events occurred frequently during his ministry proving that he is not just a man, but also God. The gospels are full of miraculous stories of Jesus’ miracles.
For example:
He fed five thousand people with five loaves of bread and two fish.
He walked on the water of a stormy lake.
He commanded the waves and wind to be still and they obeyed.
He healed multitudes of people with various infirmities.
He raised people who had died back to life.
He commanded demons to leave inflicted people, and they had to obey.
Jesus demonstrated his supernatural authority over the basic elements and over all other aspects of creation. Only God has this kind of authority over creation. And then came the final demonstration. His Godly love for us. Jesus did not use his power to protect himself but humbled himself and allowed men to take his life so that he could pay for our sins. Then his Father raised him from the dead and gave him all authority over heaven and earth.
The evidence is clear. Jesus is God! No other can claim this truth.
