Pretty simple. The name of God was given so that we might know him. Yahweh is the Hebrew name of God. The one who called the disciples and said we are God's children could call God Abba (Father) shows that there is nothing to avoid in calling out His name. This is not informality or lack of respect, but reflects how God draws close to His people.
