Upon digging further, I also found 1 John 5:14-15, “And this is the confidence that we have toward him, that if we ask anything according to his will he hears us. And if we know that he hears us in whatever we ask, we know that we have the requests that we have asked of him.” So it’s not just whatever we ask; it’s whatever we ask according to His will. Our confidence in prayer then can be held in promises He has already given us in Scripture, or occasionally devine personal revelation. But that left me lost about prayers for healing or personal requests. What is the point praying for our health or desires, when we have no power to change God’s will?
