“Or in another way; Frequently are men delivered from the hands of the enemy, but not without fear. For when fear and peril have gone before, and a man is then plucked from the enemies’ hand, he is delivered indeed, but not without fear. Therefore said he, that the coming of Christ caused us to be snatched from the enemies’ hands without fear. For we suffered not from their evil designs, but He suddenly parting us from them, hath led us out to our own allotted resting place.”

“Having said that a horn of salvation had risen up to us from the house of David, he shews that through it we are partakers of His glory, and escape the assaults of the enemy. As he says, That being delivered out of the hands of our enemies, we might serve him without fear. The two things above mentioned will not easily be found united. For many escape danger, but fail of a glorious life, as criminals discharged from prison by the king’s mercy. On the other hand, some reap glory, but are compelled for its sake to encounter dangers, as soldiers in war embracing a life of honour are oftentimes in the greatest peril. But the horn brings both safety and glory. Safety indeed as it rescues us from the hands of our enemies, not slightly but in a wonderful manner, insomuch that we have no more fear, which arc his very words; that being delivered from the hand of our enemies, we might serve him without fear.”

“Being delivered, etc. - The salvation brought by Jesus Christ, consists in the following things: - 1. We are to be delivered out of the hand of our enemies, and from all that hate us; so that sin shall neither have dominion over us, nor existence in us. 2. We are to worship God, λατρευειν, to render him that service and adoration which the letter and spirit of his religion require. 3. Ye are to live in holiness, a strict inward conformity to the mind of Christ - and righteousness, a full outward conformity to the precepts of the Gospel. 4. This is to be done before God, under the continual influence and support of his grace, and with a constant evidence of his presence and approbation. 5. This state is a state of true happiness - it is without fear. Sin is all cast out, holiness is brought in; God's power upholds, and his approbation cheers and comforts, the believing heart. Thus misery is precluded, and happiness established. 6. This blessedness is to continue as long as we exist - all the days of our life, in all ages, in all situations, and in all circumstances. What a pity to have lived so long without God in the world, when so much happiness and glory are to be enjoyed in union with him! Της ζωης, in the last clause, is omitted by many MSS., versions, and fathers. Griesbach has left it out of the text: however, it is but of small importance whether we read all our days, or, all the days of our life.”

“That he would grant us, &c.--How comprehensive is the view here given! (1) The purpose of all redemption--"that we should serve Him"--that is, "the Lord God of Israel" (Luk 1:68). The word signifies religious service distinctively--"the priesthood of the New Testament" [BENGEL]. (2) The nature of this service--"in holiness and righteousness before Him" (Luk 1:75) --or, as in His presence (compare Psa 56:13). (3) Its freedom--"being delivered out of the hand of our enemies." (4) Its fearlessness--"might serve Him without fear." (5) Its duration--"all the days of our life."”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
