Zacharias said to the angel, "How can I be sure of this? For I am an old man, and my wife is well advanced in years."
      While Zacharias was burning incense in the temple, the whole multitude of the people were praying without,Luke 1:10; Luke 1:10. Dr. Lightfoot says that there were constantly in the temple, at the hour of prayer, the priests of the course that then served, and, if it were the sabbath day, those of that course also that had been in waiting the week before, and the Levites that served under the priests, and the men of the station, as the Rabbin call them, who were the representatives of the people, in putting their hands upon the head of the sacrifices, and many besides, who, moved by devotion, left their employments, for that time, to be present at the service of God; and those would make up a great multitude, especially on sabbaths and feast-days: now these all addressed themselves to their devotions (in mental prayer, for their voice was not heard), when by the tinkling of a bell they had notice that the priest was gone in to burn incense. Now observe here, (1.) That the true Israel of God always were a praying people; and prayer is the great and principal piece of service by which we give honour to God, fetch in favours from him, and keep up our communion with him. (2.) That then, when ritual and ceremonial appointments were in full force, as this of burning incense, yet moral and spiritual duties were required to go along with them, and were principally looked at. David knew that when he was at a distance from the altar his prayer might be heard without incense, for it might be directed before God as incense,Psalms 141:2. But, when he was compassing the altar, the incense could not be accepted without prayer, any more than the shell without the kernel. (3.) That is not enough for us to be where God is worshipped, if our hearts do not join in the worship, and go along with the minister, in all the parts of it. If he burn the incense ever so well, in the most pertinent, judicious, lively prayer, if we be not at the same time praying in concurrence with him, what will it avail us? (4.) All the prayers we offer up to God here in his courts are acceptable and successful only in virtue of the incense of Christ's intercession in the temple of God above. To this usage in the temple-service there seems to be an allusion (Revelation 8:1; Revelation 8:3; Revelation 8:4), where we find that there was silence in heaven, as there was in the temple, for half an hour, while the people were silently lifting up their hearts to God in prayer; and that there was an angel, the angel of the covenant, who offered up much incense with the prayers of all saints before the throne. We cannot expect an interest in Christ's intercession if we do not pray, and pray with our spirits, and continue instant in prayer. Nor can we expect that the best of our prayers should gain acceptance, and bring in an answer of peace, but through the mediation of Christ, who ever lives, making intercession.
