Psalms 93:1 KJV
The LORD reigneth, he is clothed with majesty; the LORD is clothed with strength, wherewith he hath girded himself: the world also is stablished, that it cannot be moved.
I think it was Thomas Watson who said, "Let the Christian be content in this, that God should rule the world."
There could be
Nothing more important
Nothing more powerful
Nothing more comforting
Than to have the firm conviction that "The LORD reigneth..."
This world likes to challenge that conviction.
The strife that is in the world
The current political circumstances
The mockery of the faith in the media
All call our conviction into question
Then there are those things that come up in our own minds to challenge our conviction:
Why don't more people believe?
Why doesn't the Lord answer (positively) every prayer?
Why do God's people suffer so in this world?
These and a hundred questions like them root down to the core of our convictions and test and prove them.
But when our conviction is solid, and we have this confidence, that regardless of how it appears with the human eye, "The LORD reigneth..." there is such power that flows in through and for that believer.
