John the Baptist was annointed for the ministry from his mother's womb. To prepare the ways of the Lord. On the other hand we see Jesus Christ was baptized and the signs from heaven was witness to confirm to everyone he was a son of God. Jesus had fasted 40 days and 40 nights and he encounter the devil in the wilderness and after the temptation, he moved in supernatural healing the sick, casting demons from people. We need this power to bring the kingdom of God here on earth as it in heaven.
