Hebrews 2:13

Heb. 2:13. And again, I will put my trust in him. And again, Behold I and the children which God hath given me.

The John 14:27 sermon "On the Peace which Christ Gives His True Followers" explains Hebrews 2:13:

Men in their wills or testaments most commonly give their estates to their children. So believers are in Scripture represented as Christ's children. Hebrews 2:13, "Behold I, and the children which God hath given me." Men most commonly make their wills a little before their death. So Christ did, in a very special and solemn manner, make over and confirm to his disciples the blessings of the new covenant, on the evening before the day of his crucifixion, in that discourse of which my test is a part. The promises of the new covenant were never so particularly expressed, and so solemnly given forth by Christ in all the time that he was upon earth, as in this discourse. Christ promises them mansions in his Father's house, John 14:1-3. Here he promises them whatever blessings they should need and ask in his name, chap. John 15:7; John 14:23; John 14:24. Here he does more solemnly and fully than anywhere else, give forth and confirm the promise of the Holy Spirit, which is the sum of the blessings of the covenant of grace, John 14:16; John 17:26; John 15:25; John 16:7. Here he promises them his own and his Father's gracious presence and favor, chap. John 14:18; John 19:20; John 19:21. Here he promises them peace in the text. Here he promises them his joy, chap. John 15:11. Here he promises grace to bring forth holy fruits, John 15:11. And victory over the world, chap. John 16:33. And indeed there seems to be nowhere else so full and complete an edition of the covenant of grace in the whole Bible, as in this dying discourse of Christ with his eleven true disciples.
