Do We Trust God?

After God said to Abram, "I will give you this land..," Abram questions God's word by asking, "...how do I know that I will possess it?" Do we really trust God will make good on his promises, on his word? What does it mean to trust God? Trust is a difficult thing to give, even to God, because it requires a level of vulnerability and intimacy. God calls us to trust him, his word, so as to draw into a closer, intimate relationship with him.
