you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. -1 Pet 2:5
In the above verse, Peter describes the spiritual house God is building. Jesus is the perfect foundation stone God has chosen for the house. Those who trust in Him are living stones which also used to build the house. In addition, we individually serve as both the priests and the spiritual sacrifices, our lives offered to the builder.
In the time of olden days, the first Temple was a physical building, which was constructed out of great blocks of hewn stone, but in new era, Christians are a spiritual house, and all believers are living stones that are being assembled together as a dwelling-place for God, with the Lord Jesus being the chief Cornerstone.
In the old era, it was the priests who were able to represent God to man and who made a petition to God, for man, and only the High Priest was permitted to enter into the presence of the Lord God.
But now Christ is our High Priest for His death tore down the barrier between man and God, so that all who believe in His name can come boldly to the throne of grace to stand in the very presence of the Father through Jesus.” Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.” (Hebrews 4:16).
Prayer: Heavenly Father, thank You for accepting me in Christ and that through Him I can come boldly into Your presence, to offer my sacrifice of praise to You. In the name of Jesus, Amen.
