Any and every time is a perfect time for prayer.
Prayer is the breathe of the soul and it is unfortunate that we do not pray as often as The Bible tells us that we should. Many of us know and quote 1 Thessalonians 5:17 which says "pray without ceasing" and yet we hardly do.
Make time to pray/talk to The LORD. Do not wait until there is an issue, or you need something to pray. Praying is talking to The LORD. Speak to Him reverently, respectfully and often. If you have a best friend/spouse or significant other that you love and adore, you want to spend every waking moment with that person, so why would time with The LORD be anything less? Practice praying your way through the day today and every day.
