"O taste and see that the Lord is good: blessed is the man that trusteth in him. "
(Psalm 34:8)
Open wide your mouth, and God shall fill it!
To receive their nourishment, the baby bird must first open wide its' mouth.
For us to receive our petitions; we must open wide our hearts in faith towards God.
God will fill out mouths with good things if we stay loyal to Him.
Obedience brings blessings.
