If we [are willing to] accept the testimony of people about matters, [surely we ought to accept that] the testimony of God is more reliable; because the testimony of God is that He has presented [confirming] testimony concerning [the identity and mission of] His Son.

The person who [sincerely] believes in God's Son has the evidence [of it] within his heart, [confirming God's testimony]. The person who does not believe God [i.e., what He says about Jesus], accuses Him of lying, because he has not accepted the [irrefutable] testimony of God concerning [the identity and mission of] His Son.

And the apostles [See verses 14-15] went out and preached everywhere. The Lord worked with them and confirmed the message [i.e., verified that it was true] by means of the [miraculous] signs which accompanied their ministry. May it be so.

He said to them, "Do not take anything with you during your travels; not [even] a walking stick [Note: By comparing this and the restriction in Matt. 10:10, with the permission given in Mark 6:8, the harmony seems to be "if you do not already have a walking stick, do not get one"], or a traveling bag [for personal belongings], or food, or money, or [even] two coats [Note: Mark 6:9 says, "take only one coat" confirming the idea that Jesus was saying, in effect, "do not take anything extra, go just as you are"].

And the God who bestows every unearned favor [upon His people], who invited you to partake of His eternal splendor through Christ Jesus, will restore, confirm, strengthen and stabilize you people [in the faith], after you have gone through a brief time of suffering.

And we have the message of the prophets [confirmed to us] as more certain [than ever]. So, you will do well to pay careful attention to it, as [you would] to a lamp in a dark place, until the day dawns and the morning star rises in your hearts [Note: This probably refers to the beginning of the Gospel age, when people would become enlightened to its message].

The person who has accepted Jesus' testimony has confirmed this [fact], that God is truthful.

Then the Jews also joined in [making] the charge, and confirmed all the facts that were being presented.

He received the sign of circumcision as a seal [confirming] that he had been [considered] righteous because of the faith he had before being circumcised. Thus, he became the [spiritual] father of all people who believe [in God], even though they have not been circumcised, so that they could be considered righteous [by their faith].

I am telling [you] the truth in Christ [i.e., since I am a Christian]; I am not lying. My conscience, [confirmed] by the Holy Spirit, supports my statements [as true],

For I tell you that Christ was [appointed] to be a servant of the circumcised ones [i.e., the Jews], in order to uphold the truth of God. This was so He could confirm [as valid] the promises made to our forefathers,

how will we escape [punishment] if we neglect such a great salvation? [For it was] first announced [to people] by the Lord and then confirmed to us [i.e., the writer and other Christians] by those who heard Him [i.e., the original apostles].

Since God wanted to show conclusively to those who would inherit the promise [i.e., Abraham and all of his spiritual descendants], how unchangeable His purpose was, He confirmed it with an oath.
