God cares for His own
"In a desert land he found him, in a barren and howling waste. He shielded him and cared for him; he guarded him as the apple of his eye, like an eagle that stirs up its nest and hovers over its young, that spreads its wings to catch them and carries them on its pinions. The LORD alone led him; no foreign god was with him" (Deuteronomy 32:10-12).
As a father cares for his children, so God cares for His own
God is the source of all comfort
"Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God" (2 Corinthians 1:3-4).
Cast your concerns on the Lord, for He will support you
"Cast your cares on the LORD and he will sustain you; he will never let the righteous fall" (Psalm 55:22).
