Judges 13:19 So Manoah took a kid with a meat offering, and offered it upon a rock to the Lord: and the angel did wondrously, and Manoah and his wife looked on.
The Angel of the Lord (the preincarnate Son) appeared to Manoah and his wife, announcing they would conceive a son who would become a Nazirite to God from the womb (no strong drink). He would begin to save Israel from the hand of the Philistines. This would be Samson, whose God-given strength brought victories over the enemy. The Lord is raising up another Deliver to bring a temporary peace to Israel. By the way, a permanent peace will not come until the Son of God is born as a man, lives, dies, rises, and comes again. Samson and the Judges are foreshadowing pictures of the Savior of all.
Manoah’s response to the Lord’s appearance and promise is to worship by bringing a grain offering to the Lord. He and his wife believed the promise and thanked God. A grain offering consisted of flour mixed with olive oil, shaped into a cake, and then burned along with a burnt offering. It was offered to God as a sign of honor, respect, and worship. It showed that their food came from God and they owed their lives to Him. It was an outward showing of what was in the heart of faith. This offering was accepted by the Lord as the angel rose up in the flames.
Our whole life is an offering of worship and thanks to God for sending His Son to be our Deliverer. We don’t offer blood sacrifices, or grain offerings, since Jesus came and sacrificed Himself for us. But we do worship in spirit and truth, and we offer of our time, abilities, and money in service to others. “For everything give thanks.” Jesus paid the final, once for all, sacrifice, and we respond with lives of worship, praise, and service.
