There are a number of reasons that miracles might convince someone that God exists.

• When something happens that breaks the laws of science it can be hard to explain. When miracles happen, they can lead people to feel God is the only explanation, therefore he must exist.
• They offer evidence that God is still at work in the world. Miracles didn't just happen in the Bible, but are real today, which proves that God must exist.
• They offer evidence of God's nature. He is benevolent: he loves everybody and wants to have a relationship with people. He is also omnipotent, all-powerful, breaking the laws of science. This brings people comfort and increases their faith.

Jesus knew that people begin to believe in God when they witness miracles. John 4: 43-54 tells the story of a time when Jesus healed someone. A government official approached and asked him to heal his child, who was on the brink of dying.

Jesus said to him:

“None of you will ever believe unless you see miracles and wonders.” John 4:48

Indeed, the official returned home and he and his entire family believed from this point on.

Additional stories can be found in the Bible, with people changing their ideas about God when they encounter a miracle. One example is Daniel's story of the miracle in the lions' den.

Daniel 6 tells of how he refused to bow down to the Babylonian gods and was thrown into the lions' den as punishment. He survived the whole night, which the king recognised as a miracle. From this point on, the king's subjects were made to respect Daniel's God.
