Isai 28:16 Therefore thus saith the Lord GOD, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner [stone], a sure foundation: he that believeth shall not make haste.
This "Stone" has been tried and tested and has stood unchanged and unchangeable. He was "in all points tempted like as we are, yet without sin. Let us therefore come boldly unto the throne of grace that we may obtain mercy and find grace to help in time of need." (Heb 4:16) The church is "built upon the foundation of the apostles and the prophets, Jesus Christ being the Chief Corner Stone." We, too, are tried and tested as to our faith, but if our faith is fixed upon the "Tried Stone" as revealed in His Word, we shall never fail.
Oh, Thou "Tested and Tried Stone", our Lord, we trust in Thee and joyfully commit our all to Thee. Amen.
