Psalm 9:10 - And those who know your name trust in you, for you, O Lord, have not forsaken those who seek you.
There is an element of trust that requires a knowledge of who God is. In Scripture, the name of the Lord represents His character and nature. Therefore, in order for us to completely entrust ourselves into Him, it is important that we know who we are giving ourselves to. Otherwise, there is no depth to the relationship and when hard times fall, our faith may waiver.
Imagine a young couple who fell in love "at first sight" and decided to get married that same day. They knew little about each other, nothing of their background, or how they would handle different situations. After the initial "buzz" wore off, what do you think would happen to the couple? Chances are, they would find out that their relationship was not what they thought it was.
In the same way, if we think that we have faith without having a knowledge of who God is, we carry the risk of having wrong perceptions about God. We then might carry with that wrong expectations. Then, when God does not meet our wrong expectations of Him, we blame Him.
However, when we know the character of God, the natural result is trust, because in His nature is faithfulness, trustworthiness, truth, honor, etc. By knowing God's character, represented by His name, we are given reassurance in times of trouble.
The challenge today is to look through Scripture at some of the names of God and see how He is that name in your life.
