hope - yahal - wait, expect, tarry: patience
Send out your light and your truth; let them lead me; let them bring me to your holy hill to your dwelling. Then I will go to the altar of God, my exceeding joy. And I will praise you with the lyre, O God, my God.
Why are you cast down, O my soul, and why are you in turmoil with me? Hope in God, for I will praise him, my salvation and my God! Ps 43:3-5
It seems the entire purpose of our walk with God, of our faith development is to get closer to God. Interestingly, I have been taught that the priority is good behavior, as if it alone is right-ness. Right living only comes from a heart right with God. Here the psalmist looks to God's light (concretely so as to light the day or metaphorically to include "lightness" or happiness) and his truth (which emanates from God and is about God) as his source for hope because it leads to God himself. The purpose of the that truth is to light the path to the dwelling place of God. Think of it as showing the way to a relationship with God.
We tend to look for our answers, our salvation in many far places from God. Sometimes, we look for our answers in the things of God - his Word, his Church - which can be helpful, but they are not God. It is where we should place the source of our answers that is the real pursuit. Our answers, our desires, our need for a safe place is actually in a sacred relationship with the Father. Seek him first...and all these will be added..
Father, open my eyes to the truth you shine a light on. No other revelation but what comes from you, please. Amen!
