Charles Spurgeon Commentary 1 Chronicles 22:13

"Then shalt thou prosper, if thou observe to do the statutes and the ordinances which Jehovah charged Moses with concerning Israel: be strong, and of good courage; fear not, neither be dismayed." — 1 Chronicles 22:13 (ASV)

Then shalt thou prosper, if thou takest heed to fulfill the statutes and judgments which the LORD charged Moses and concerning Israel: be strong and of good courage; dread not, nor be dismayed.

It is a great thing for a Christian to keep his courage up; and especially for a builder of the Church of God to be always brave, and with a steadfast heart to do God's will, come what may.
