"Pray continually" (1 Thess 5:17).
"And pray in the Spirit on all occasions with all kinds of prayers and requests" (Ephesians 6:18).
If I did not use a prayer journal, I would forget so many that I really want to pray for. So, I really encourage you to use some type of a prayer journal to help you remember.
3. "Don't know how to pray about it."
Romans 8:26b says: We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express.
