Hope is the desire for something to occur while trust is the absolute knowledge that something will occur. Hope contains an element of doubt while Trust is void of doubt.
We are not to place our hope in the Lord, we are to place our Trust in the Lord for Trust is the nutrient necessary to grow faith.
For God is absolute in all realms and respects, including His Love for us; to provide for us.
Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. -Matthew 26:6.
Even the birds trust in God. But humans, the God like creature, the children of God, the greatest gift created by God, we find it difficult to trust in Him.
We hope therefore we worry.
