Waiting For God
I remain confident of this:
I will see the goodness of the Lord
in the land of the living.
Wait for the Lord;
be strong and take heart
and wait for the Lord. Psalm 27:13-14
David prays these lines at the end of a long prayer (read all of Psalm 27). In that prayer he wavers between confidence ("whom shall I fear!") and concern ("do not hide your face from me!") - much like the rest of us. But these verses above are where he ends up - with believing God will show up in this life (seeing goodness in the land of the living) and then talking to himself and encouraging himself to have patience ("wait for the Lord").
David seems to think it's fine to pray with confidence and anxiety at the same time, and apparently his belief in God doesn't mean he doesn't have to give himself a pep-talk every now and then. This is honest prayer - letting everything out of the bag and putting it before God. David understands that it's hard to wait for answers, that expectations sometimes get smashed, but that God is still good and worth praying to one way or the other.
Why don't you take some time to pray honestly to God, and when you get stuck, share your stuck-ness too! If you don't believe, share your doubts too! If you feel confident, tell God that too! Just put it all out there today, and then say to yourself, "Wait for the Lord; be strong and take heart, and wait for the Lord."
