Do you want to know what God is like? Then look at Jesus. Immerse yourself in the gospels of Matthew, Mark, Luke, and John to know him and know the eternal life found in him.
If you want to know how God reacts to people, look at how Jesus react to people.
If you want to know what God thinks of you, look at how Jesus relates to people.
If you want to know what God loves, look at who Jesus loves.
If something you think or have heard is in contradiction to what Jesus taught and how he acted, then we know it is not of God.
