Rest in the Lord means to trust in Him completely. Whether or not you hear His voice or feel His hand in yours does not matter as much as knowing in your heart and mind that He is with you. Resting in the Lord means you don't have to worry about anything; after all, He is the Creator, He made the heaven and earth and everything and everyone in His creation. He made you and your family, your parents, spouse and children. The Lord God wants you to be at rest, knowing that He is with you every step of the way. "do not fear for I am with you" Isa 41:10. We spend too much time either trying to please ourselves and or trying to please God by doing what we think pleases Him. What pleases Him is letting Him be in control when you cannot and should not. This Thanksgiving season, gives thanks and praise to the Lord God Jesus Christ and rest in Him.
My favorite Psalm is Psalm 103
"Praise the Lord, O my soul; all my inmost
being, praise his holy name. Praise the Lord, O my soul, and forget not
all his benefits - who forgives all your sins and heals all your
diseases, who redeems your life from the pit and crowns you with love
and compassion, who satisfies your desires with good things so that your
youth is renewed like the eagle's."
