Psalms 86:16,17

While we here behold Christ as God's servant and God's chosen, surely every believer in him may humbly adopt this prayer and ask for a token of good. And what good equal to the token of God's Spirit, the seal of the covenant, union with Christ, and fellowship with the Father, and with his blessed Son? Oh, for such blessed tokens, whereby believers are sealed unto the day of redemption! Ephesians 1:13.
