I’ve always equated worry to the fear of the future and fear of God not protecting us from what we will face, but there are some other possible reasons for worry that I found interesting.
Worry may be a symptom of a bigger problem. Sometimes it’s a lack of gratitude for the way God has cared for us in the past. Or perhaps it’s a lack of faith that God really is trustworthy. Or it may be a refusal to depend on God instead of ourselves… Don’t let worries hold you back from what God may be trying to teach you. He invites you to bring your anxious thoughts directly to Him (Phil. 4:6).
