King David had an honest, open, and real relationship with God, which gave him the freedom to express his heart. When he released through prayer his anger, hurt, fear, or hopelessness, his heart would be settled and he could begin praising, trusting, and believing his heavenly Father, even when his circumstances did not quickly change. David cast the negative on the Lord, and the Lord assisted; helping and supporting him by refilling his heart with His positive Spirit of praise and encouraging truth.
God is the same today as He was yesterday! He desires to carry the weight of our burdens and keep us stepping forward in our Spiritual walk of being connected to Jesus and renewed faith.
“Cast your burden on the Lord[releasing the weight of it] and He will sustain you” (Psalm 55:22a).
