Those who trust in the Lord are like Mount Zion, which cannot be moved, but abides forever. Psalm 125:1Trust. The Hebrew carries the ideas of being bold, confident, secure, and sure.
Those who trust in the Lord will not waver, slip, shake or fall.
I usually do a lot of wavering, slipping and shaking but when I read the next verse…
As the mountains surround Jerusalem, so the Lord surrounds his people, from this time forth and forevermore. Psalm 125:2
God surrounds us, protects us, shelters us, now and forever.
When I grasp that, trusting Him, with bold, confident assurance, is easy.
