Christian author, O. Hallesby wrote:
"The air which our body requires envelops us on every hand. The air itself seeks to enter our bodies and, for this reason, exerts pressure upon us...The air which our souls need also envelops all of us at all times and on all sides. God is round about us in Christ on every hand, with His many-sided and all sufficient grace. All we need to do it to open our hearts. Prayer is the breath of the soul, the organ by which we receive Christ into our parched and withered hearts...As air enters in quietly when we breathe, and does its normal work in our lungs, so Jesus enters quietly into our hearts, and does His blessed work there."
Inhale His grace and mercy; exhale your worries and trials. Breathe Him in so He may sustain you. And do it without ceasing. 1 Thessalonians 5:17
I found the above quote in a book by Karol Ladd, The Power of a Positive Mom. I really needed to be reminded that my prayer should be continuous. It is necessary for my well being.
