Hebrews 2:1-…Now in putting everything in subjection to him, he left nothingoutside his control. At present, we do not yet see everything in subjection to him.

Believers and Churches across the world have shared the practice of listing prayer requests.  It is a great tool for corporate/personal prayer, giving a sense of unity to believe God for things we desire to see His power answer.  
Though it is great to recognize our/others needs, it is our perseverance to believe in the power of God to answer as He sees fit, that emboldens our faith in His power and might.  Because they are things I have tried to believe God for, for years on end, and at times I’ve fainted in persevering to keep praying…(Luke 18:1-8)
Which is why the passage of Hebrews above is a loving rebuke, to remind me in times of my “evil, unbelieving heart”, to be renewed back into what I know about our Lord’s character and attributes.  That Christ is always all powerful and in control, and though He may not answer as I hoped, I shouldn’t undermine Him being in absolute control. (Isaiah 55:8-9, Hebrews 3:12)
In waiting on the Lord, many times it’s in the “waiting period” that He reveals to us what needs to change, and that is our mind and heart, not necessarily what we’ve been praying about.  We may mentally acknowledge God being in control, wanting Him to fix every issue, when in reality He is interested in conforming us to Christ, “learning obedience through suffering” in whatever it is…(Hebrews 5:8)
So it’s possible to miss the relational aspect of prayer, when the relationship is the goal of God’s heart in salvation.  It is through a relationship that loves Him for who He is, rather than what He is able to do.  Because God could eliminate all ailments of hardship and toil because of His power, but how would that conform us to Christ and live by faith?  (2 Corinthians 5:17-21)
All things are in subjection to God, though we presently don’t see it as so.  Faith cultivates intimacy and security, affirming that He is in control despite what we see before us.  In His Love, Ld
