This is really beautiful. I can feel your passion in your words. I noticed that some of the lines seemed to have the wrong tense but by switching it just a tad I think you could still have it fit your rhythm pattern. For example you might want to adjust the first two lines to something like this:(just to help the flow)
Do you ever have problems that cross your way?
Is your heart filled with uttered dismay?
I just changed crossing to cross and does to Is.
You have a natural talent and though I'm not musical at all (I can't carry a tune in a bucket) I could almost hear you singing this beautiful message of God's love. Keep writing, for only you can write the words that God lays on your heart!
