Sam Storms writes,
People often confuse praying expectantly with praying presumptuously. Prayer is presumptuous when the person claims healing without revelatory warrant or on the unbiblical assumption that God always wills to heal…On the other hand, people pray expectantly when they humbly petition a merciful God for something they do not deserve but know that he delights to give (Luke 11:9-13; cf. Matt. 9:27-31; 20:29-34; Luke 17:13-14). Expectant prayer flows from the recognition that Jesus healed people because he loved them and felt compassion for them (Matt. 14:13-14; 20:34; Mark 1:41-42; Luke 7:11-17), a disposition that nothing in Scripture indicates has changed. (Are Miraculous Gifts for Today, 214)
Presumption is often mistaken for boldness and passivity is often born out of drawing unbiblical implications from the truth of the absolute sovereignty of God over all things.
Don’t be a presumptuous pray-er or a passive pray-er. Be an expectant one.
