For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
Yet to all who received him, to those who believed in his name, he gave the right to become children of God.
Understanding is the reward of faith. Therefore seek not understanding that though mayest believe, but believe that thou mayest understand.
And this is his command: to believe in the name of his son, Jesus Christ, and to love one another as he commanded us.
1 John 3:23
I have come into the world as a light, so that no one who believes in me should stay in darkness.
If you can? said Jesus. Everything is possible for him who believes.
All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name.
