The Lord gives strength to his people; the Lord blesses his people with peace.
In human history, those two terms have been at odds at times - you could easily cite examples of those in power with strength who have been anything but peaceful.
But we're not talking about human examples. Strength from God - that inner strength - is the perfect complement to God's inner peace.
So many times, I've needed strength and peace. It's difficult - and I'd say impossible in the final analysis - to find those things in the quality of God's strength and peace.
How does he provide this? Note the words - God "gives" strength; he "blesses" people with peace. We don't purchase or earn these things. God freely gives them. To you. To all.
