3 Bible Verses about Access To God, In Old Testament

do you also yourselves be built up living stones, a spiritual house, a holy priesthood, to offer spiritual sacrifices well pleasing to God through Jesus Christ,

But you are an elect race, a royal priesthood, a holy nation, a peculiar people, that you should declare the virtues of him who called you out of darkness into his glorious light;

and made us a kingdom, priests to God even his Father, to him be the glory and the power forever; amen.
