Jesus is laying down rules of conduct for those who have His Spirit. By the simple argument of these verses He urges us to keep our minds filled with the notion of God’s control behind everything, which means that the disciple must maintain an attitude of perfect trust and an eagerness to ask and to seek.
Notion your mind with the idea that God is there. If once the mind is notioned along that line, then when you are in difficulties it is as easy as breathing to remember – Why, my Father knows all about it! It is not an effort, it comes naturally when perplexities press. Before, you used to go to this person and that, but now the notion of the Divine control is forming so powerfully in you that you go to God about it. Jesus is laying down the rules of conduct for those who have His Spirit, and it works on this principle – God is my Father, He loves me, I shall never think of anything He will forget, why should I worry?
There are times, says Jesus, when God cannot lift the darkness from you, but trust Him. God will appear like an unkind friend, but He is not; He will appear like an unnatural Father, but He is not; He will appear like an unjust judge, but He is not. Keep the notion of the mind of God behind all things strong and growing. Nothing happens in any particular unless God’s will is behind it, therefore you can rest in perfect confidence in Him. Prayer is not only asking, but an attitude of mind which produces the atmosphere in which asking is perfectly natural. "Ask, and it shall be given you."
