In Psalms, it is written: “Open wide your mouth, and I will fill it;” (Psalms 81:11.)
“You are My son… Ask it of Me, and I will make nations your estate.” (Psalm 2:7-8)
God says to everyone: “My child, do not be content. Ask of Me; request everything.”
When one asks of the One who has the power to give, it is worthwhile to ask for the greatest things one can think of.
The wider we open our mouths, the more they will be filled.
–Rabbi Adin Steinsaltz
