"You need Me every moment. Your awareness of your constant need for Me is your greatest strength. Your neediness, properly handled, is a link to My Presence. However, there are pitfalls that you must be on guard against: self-pity, self-preoccupation, giving up. Your inadequacy presents you with a continual choice - deep dependence on Me, or despair. The emptiness you feel within will be filled either with problems or with My Presence. Make Me central in your consciousness by praying continually: simple short prayers flowing out of the present moment. Use My name liberally, to remind you of My Presence. Keep on asking and you will receive, so that your gladness may be full and complete."
I Thessalonians 5:17 - "Pray continually."
John 16:24 (Amp) - "Up to this time you have not asked a (single) thing in My Name (as pertaining to all that I AM); but now ask and keep on asking and you will receive, so that your joy (gladness, delight) may be full and complete."
