In his letter to Rome, the Apostle Paul instruct the new followers of Christ Jesus to “be constant in prayer" One very unique thing about most of the epistles of Paul is that they start with prayer or the acknowledgement of other in his prayer.
In Romans 1:8 Paul start addressing those called to be saint with
“First, I thank my God through Jesus Christ for all of you”
In 1 Corinthians 1:4 Paul states
“I thank my God always on your behalf, for the grace of God which
is given you by Jesus Christ;”
In fact in all of his epistles (letters) Paul either speaks directly to praying continually (unceasing) or alludes to doing so. It’s very important that we see prayer as not just something we do, but something we do with God. Prayer is how we commune with God, without prayer there can be no relationship with God through Christ Jesus.
At this point we see prayer as important but not Omni-important, but this should quickly change, in 1 Thessalonians 5:17, Paul writes very distinctly “Pray without ceasing” Now if we really seek to develop an understanding of this we must have at least once questioned after reading this said to ourselves “How do I pray without ceasing?”. It is this question that brings revelation into what (on a spiritual level) Paul was trying to say to us.
My mind immediately goes to Bryon Cage’s song “Breathe” in that prayer must be that very thing for us, it must come to us as simple as “the Air We Breathe” We must find ourselves praying when we walk down the street, when we seat waiting for a bus to get to work, even while praying, we must find our mind wondering to seek communion with God in prayer.
Please understand this is not a exercise in discipline where we say I’m walking I must pray, I have free time I should be praying, its much more, This is a state of mind in your spiritual life where prayer comes natural, without thought without conscious efforts, as if it was the very Air you Breathe.
You see the question isn’t how we can possibly pray all the time; the question is what is praying all the time? To pray without ceasing is not praying or thinking about God instead of spending time with our families. To pray without ceasing does not mean to think about God in contrast to thinking about other things in life. To pray without ceasing means living our entire life in the presence of God. It's not instead of spending time with your family, it spending time with your family while being in the presence of God.
Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God. (1 Corinthians 10:31) KJV
