39 But we are not of those who draw back to perdition, but of those who believe to the saving of the soul.
The Holy Spirit now moves from future considerations to the what believers were facing in the first century.
There is a connection between a weak faith and withdrawal from a faithful walk with the Lord. There is a similarity between the Christian life and the exodus generation (He 3:6-4:13).
39 But we [emphatic, including the author] are not of those who draw back
“Draw back” does not refer to apostasy but contextually to the failure to be consistently true to what God says (Ga 2:12). The class of those who draw back contrasts with the “faith” class. The author of Hebrews fears that some may have misunderstood the warning of the previous verse (He 10:38).
to perdition [ruin],
“Perdition” here is not hell; this is not eternal destruction of the soul. This word means ruin. The term can refer either to either eternal destruction in hell or to temporal discipline. To draw back will ruin the believer who does this in his present life. Those believers “who draw back” will face temporal disciple from God.
The believer cannot draw back to eternal ruin. However, the Christian will ruin their testimony of walking by faith and keeping the clarity of their message if they minimize the finished work of Christ.
but of those who believe to the saving of the soul [life].
The word “saving” in the Greek does not always refer to saving the soul for eternity. It has a range of meanings which include saving the consistent life of the believer. Peter cried while walking on the sea, “Lord, save me.” He meant save me from drowning. The salvation here is the saving the believer from ruining his Christian life. This phrase has nothing to do with the conversion of the soul. The point is that the believer is to careful not to lose his or her reward.
The word “soul” can mean simply normal day-by-day life. Here the meaning is the saving of one’s daily life (He 10:32-39). If one lives by faith during times of duress, then he will receive reward from God. This is the point of the next chapters (He 11 and 12). Thus, the “saving of the soul” here has to do with ruining the Christian life. The believer will have wasted opportunity for rich reward in heaven.
The Christian can lose his or her reward by not remaining true to truth.
The purpose of the conclusion of Hebrews 10 is to warn believers of God’s disciplining them for distorting doctrine and walking away from a consistent Christian life. Under duress a believer must not give way to their personal pain.
The point of the concluding verses of chapter 10 is not apostasy but the danger of willful departing from the will of God for believers.
