their fathers
with all their heart and with all their soul,"[725] is left the record
to his honour,--"Asa's heart was perfect with the Lord all his
days."[726] And finally, as one heart is this sign a Covenant token.
Contrasted with the heart in its natural sinful condition, which is
deceitful above all things and desperately wicked, it is constituted a
reprover of those who, vowing to the Lord, swear deceitfully. Different
from the double heart vainly attempting at once to do homage to God and
mammon, it is wholly devoted to the Lord. And due to the operation of
the Spirit of God, it is disposed to unite with others his like
workmanship in faithfully resolving together, and jointly endeavouring
to promote his glory. This the Lord himself conferred, when, upon the
occasion of Hezekiah commanding all Israel to keep the passover, it was
in his heart to make a covenant with the Lord God of Israel, that his
fierce wrath might turn away from them. "Also, in Judah, the hand of God
was to give them one heart, to do the commandment of the king and of the
princes, by the word of the Lord."[727] This the Lord also promised,
when he said, "I will give them one heart, and one way, that they may
fear me for ever, for the good of them, and of their children after
them: and I will make an everlasting covenant with them, that I will not
turn away from them to do them good; but I will put my fear in their
hearts, that they shall not depart from me."[728] And this he has often
made his people to experience, as on the day of Pentecost, when the
multitude of them that believed were of one heart and of one soul; and
when by casting their effects into one common fund, they furnished, of
their common interest in one gracious inheritance, the most affecting
emblem that men have given. But, finally,

Christ was given for a sign of God's Covenant. A prophet, by
inspiration, had exclaimed, "Behold, I and the children whom the Lord
hath given me are for signs and for wonders in Israel from the Lord of
hosts, which dwelleth in mount Zion."[729] And by an apostle, these
words are represented as employed by the Saviour, having in union with
the Divine nature the nature of man.[730] In mount Zion, the Lord of
hosts dwells as a covenant God. His children, a holy priesthood, are
from him as a covenant sign; and from him also, as the most
distinguished covenant sign, is his Son--the great high priest of our
profession, himself sanctified by suffering. Th
