We have a "default position": PRAYER
Genesis 24:2-3, 9
Numbers 30:2
Matthew 5:37
Not keeping promises will not only allow us to lose our testimony within the church, but will also destroy our testimony (and the church's testimony) to the non-church world.
God will keep His promises:
1) To never leave us nor forsake us
2) To always be there for us
3) Forgiveness of sin through our belief in the sacrifice made by Jesus
