What does "Deep Cries Out to Deep” mean?

There is a new song that the Worship Team at Abundant Life Fellowship has been working on. As you learn this song and give Him praise through it, our prayer is that you let go of your deep and let it call out to the Deep in God. Here is some background to the biblical roots of the song with a link to the music video done by Bethel Church at the bottom. Background for the Background: In Numbers 16 the Bible records an event in the life of a man named Korah. He was of the tribe of Levi and therefore set apart to be a member of the priesthood in Israel. He rebuked Moses, saying: " You have gone too far! The whole community is holy, every one of them, and the LORD is with them. Why then do you set yourselves above the LORD's assembly? " -Numbers 16:3 He resented Moses' and Aaron's authority, and felt that he and his supporters could lead the Israelites more effectively. Later in the chapter, the earth opens underneath him and swallows him along with the others ...

Abundant Life Fellowship Boonville NY: Church Fire, Easter Hope, and a Growing Church Without a Building

Where Is Abundant Life Fellowship Meeting Now? Right now, our church family is meeting at Adirondack High School in Boonville, NY , as we continue worshiping together in this displaced season. Adirondack High School is located at 8181 State Route 294, Boonville, NY 13309 . We may not be in our usual building, but we are still the same body of believers. In some ways, this season has clarified something the church always needs to remember: A sanctuary can be lost. A building can be damaged. A meeting place can change. But the Church of Jesus Christ remains. The Church Is Not a Building That truth is easy to say when life is normal. It becomes much more real when your church building is gone. The New Testament reminds us that the church is not brick, wood, carpet, or stained glass. The church is made up of redeemed people indwelt by the Holy Spirit. Buildings serve ministry, but they do not define it. That means Abundant Life Fellowship did not end when the building was lost....

The Bible in 66 Sentences: Understanding the Whole Story of Scripture

When I was in college, I had a friend named Maris who asked, "what is each book of the bible about?" I sat down with her on the grass and went through, to the best of my ability at the time, what each book was about. It was a wonderful conversation and it has stuck with me over the years. So, I'm compiling a survey of every book of the bible with more in depth descriptions of each book below. I will plan to publish a new one every Wednesday for 66 weeks. Enjoy!

Exodus shows how God delivers His people from slavery, establishes a covenant with them, and dwells among them. Leviticus teaches that God is holy and calls His people to live in holiness through worship, obedience, and atonement. Numbers shows how Israel’s unbelief and disobedience delayed God’s promises, yet God remained faithful and continued His plan. Deuteronomy calls ...

It often appears in prayers for revival, political discussions, and calls for moral renewal. But to truly understand its meaning—and apply it faithfully—we need to look at its original context. The Setting: Solomon and the Temple 2 Chronicles 7 records a pivotal moment in Israel’s history.

At its dedication, Solomon prayed a sweeping prayer (2 Chronicles 6), asking God to hear His people whenever they turned back to Him—especially in times of sin, defeat, drought, or exile.
