God doth it to this purpose, to assure us and secure us of the inheritance. Having given us so many Heb. vi. 17, 18.securities without us, — his word, promises, covenant, oath, the revelation and discovery of his faithfulness and immutability in them all, — he is pleased also graciously to give us one within us, Isa. lix. 21, that we may have all the security we are capable of. What can more be done? He hath given us of the Holy Spirit; — in him the first-fruits of glory, the utmost pledge of his love, the earnest of all.
