"With every prayer and request, pray at all times in the Spirit"
The Bible tells us we are to pray without ceasing, but for many believers this is not understood in a practical sense. Prayer for each individual must become a daily, constant, and consistent way of living. In any given moment we are only a thought and breath from communicating with God. In a day and age when we pride ourselves on having high-speed internet connections, we also have a high-speed instant access connection with the Heavenly Father.
In the book of Psalms we get some insight into the approach that David took in praying at all times. In Psalm 4 we are reminded that he prayed before ending the day. In Psalm 5 we see him start his day in prayer. In Psalm 6 we see how he prayed in the aftermath of his failures. In Psalm 7 we read how David prayed when the pressure was on and he was under attack. In Psalm 8 he prayed when he thought of the creative power of God. In Psalm 9 we see that he prayed in times of joy. In Psalm 10 he prayed when he felt isolated.
It is safe to say that David as a lifestyle prayed without ceasing and stressed how important it is to keep the lines of communication open to God.
