Jesus instructs us to ask according to the will of God, as Paul does:
Brothers and sisters, my heart’s desire and prayer to God on behalf of my fellow Israelites is for their salvation.
Romans 10:1 NET
God does not grant the desire of the heart that wants to spend in its own pleasures (see James 4:1ff). And we blame God at times for not granting our requests because we think, carnally and crazily, that our pleasures are the will of God.
Nothing, however, is closer to God’s heart, than the salvation of all people.
