Why do we constantly check our smartphones?
Because we do everything on our phones?
That's one reason.
Here's a couple of reasons that are more subtle:
1. We want the approval of man.
2. We are bored and find focusing on one thing for long very difficult.
Both of these more subtle reasons for constant phone checking is hazardous to our spiritual health.
Pursuing the approval or glory of man keeps us from being concerned with the approval and glory of God. (John 12:42-43; 5:39-47)
Finding it difficult to focus on one thing for very long keeps us from focusing on the Scriptures and thinking deeply about the truth that sets us free and grounds us in reality. (John 8:31-32; 17:17; Psalm 1:1-3)
