Amy Carmichael ministered with children in India for over 50 years. She was impressed at an early age that "nothing is important but that which is eternal." Her book Thou Givest...They Gather is a collection of truths she gleaned from scripture.
Her insightful comment on Psalm 71:3 is helpful: "Be Thou my strong habitation whereunto I may continually resort."
One time, because of some failure, she was feeling too cast down and too ashamed to "resort" to her strong habitation. After such a defeat, the only possible thing seemed to be to stay away for a while. It seemed almost wrong to go back at once, just as if nothing had happened.
Then a child did something wrong and would not come to her. Suddenly Amy understood that the greatest wrong we can do to Love is to stay away. The word "continually" gave just the encouragement she needed.
I love the way the New Living Translation states this verse: "Be to me a protecting rock of safety, where I am always welcome."
Jesus, I'm thankful there are no exceptions to the words "continually" and "always." You always welcome me.
"For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are-yet was without sin. Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need" (Hebrews 4:15, 16).
