The Altar is a place of sacrifice. And the Temple is a place of worship or to dedicate ourselves to God.
John 17:11 I will remain in the world no longer, but they are still in the world, and I am coming to you. Holy Father, protect them by the power of[a] your name, the name you gave me, so that they may be one as we are one.
Leviticus 23:33-44 33 The LORD said to Moses, 34 “Say to the Israelites: ‘On the fifteenth day of the seventh month the LORD’s Festival of Tabernacles begins, and it lasts for seven days. 35 The first day is a sacred assembly; do no regular work. 36 For seven days present food offerings to the LORD, and on the eighth day hold a sacred assembly and present a food offering to the LORD. It is the closing special assembly; do no regular work.
37 (“‘These are the LORD’s appointed festivals, which you are to proclaim as sacred assemblies for bringing food offerings to the LORD—the burnt offerings and grain offerings, sacrifices and drink offerings required for each day. 38 These offerings are in addition to those for the LORD’s Sabbaths and[a] in addition to your gifts and whatever you have vowed and all the freewill offerings you give to the LORD.)
39 “‘So beginning with the fifteenth day of the seventh month, after you have gathered the crops of the land, celebrate the festival to the LORD for seven days; the first day is a day of sabbath rest, and the eighth day also is a day of sabbath rest. 40 On the first day you are to take branches from luxuriant trees—from palms, willows and other leafy trees—and rejoice before the LORD your God for seven days. 41Celebrate this as a festival to the LORD for seven days each year. This is to be a lasting ordinance for the generations to come; celebrate it in the seventh month. 42 Live in temporary shelters for seven days: All native-born Israelites are to live in such shelters 43 so your descendants will know that I had the Israelites live in temporary shelters when I brought them out of Egypt. I am the LORD your God.’”
44 So Moses announced to the Israelites the appointed festivals of the LORD.
The people first built the altar for them to communicate to God. Nowadays, we should set prayers as our first priority.
Genesis 8:20 Then Noah built an altar to the LORD and, taking some of all the clean animals and clean birds, he sacrificed burnt offerings on it.and where he had first built an altar. There Abram called on the name of the LORD.
Genesis 13:4 and where he had first built an altar. There Abram called on the name of the LORD.
Genesis 22:14 So Abraham called that place The LORD Will Provide. And to this day it is said, “On the mountain of the LORD it will be provided.
They give thanks through the altar, for us now through prayers.
Psalm 136:1 Give thanks to the LORD, for he is good. His love endures forever.
Job 38:6 On what were its footings set, or who laid its cornerstone—
1 John 1:9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
