“Therefore, holy brothers, you who share in a heavenly calling, consider Jesus, the apostle and high priest of our confession, 2 who was faithful to him who appointed him, just as Moses also was faithful in all God’s house. 3 For Jesus has been counted worthy of more glory than Moses—as much more glory as the builder of a house has more honor than the house itself. 4 (For every house is built by someone, but the builder of all things is God.) 5 Now Moses was faithful in all God’s house as a servant, to testify to the things that were to be spoken later, 6 but Christ is faithful over God’s house as a son. And we are his house if indeed we hold fast our confidence and our boasting in our hope” (Hebrews 3:1–6 ESV).
John Owen, English Puritan, 1680:
“[Hold Fast] signifies a careful, powerful holding any thing to it against opposition… Two things, therefore, are represented in this word. First, That great opposition will arise against this duty, against our firmitude and constancy in profession. Secondly, That great care, diligence, and endeavour are to be used in this matter or we shall fail and miscarry in it” (John Owen, An Exposition of the Epistle to the Hebrews with Preliminary Exerciations, volume 3 [Edinburgh, Scotland/Carlisle, PA: Banner of Truth Trust], p.564)
