Foundations

Way back when I first was drawn by God to seek out true worshippers, I was led to "The Fountain of Life" in Kingston, NY, where a group of elders oversaw an amazing little body of Christ.  Dale Rumble was one of the elders there; when I went looking on the internet for him now-a-days, I found out he passed away in 2010, but I was very blessed by this quote, from one of his tracts.  You will be too.
His stuff is available at www.thefountain.org

"I believe that the glory of the end-time church will be greater than that of the early church. Through hurricanes, floods, tornadoes, earthquakes, wars, economic upheaval, etc., the Lord will shake the realms of man to bring him to repentance.

. . . once more in a little while, I am going to shake the heavens and the earth, the sea also and the dry land. I will shake all the nations; and they will come with the wealth of all nations and I will fill this house with glory, says the Lord of hosts. (Haggai 2:6-7)

The church that Jesus returns for will be an overcoming body of believers who have endured great tribulation and persecution. She will be a mature bride clothed with the glory of God.

End-time Tribulation

Teaching that Jesus will return and rapture the church before the great tribulation occurs is false. Trials and tribulation are used by God to purify, strengthen and mature His people. Martyrdom is a path to glory.

. . . but we also exult in our tribulation, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope . . . . (Romans 5:3-4)

Beloved, do not be surprised at the fiery ordeal among you, which comes upon you for your testing, as though some strange thing were happening to you. (1 Peter 4:12)

. . . for if we died with Him we will also live with Him; if we endure. we will also reign with Him . . . . (2 Timothy 2:11-12)

For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison. (2 Corinthians 4:17)

. . . through many tribulations we must enter the kingdom of God. (Acts 14:22)

. . . if indeed we suffer with Him so that we may also be glorified with Him . . . . (Romans 8:17)

Many will be purged, purified and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have insight will understand. (Daniel 12:10)

And they overcame him because of the blood of the Lamb and because of the word of their testimony, and they did not love their life even when faced with death. (Revelation 12:11)

Then they will deliver you to tribulation, and will kill you, and you shall be hated by all nations because of My name . . . but the one who endures to the end shall be saved. (Matthew 24:9, 23)

The above verses of scripture express God’s agenda to restore the church and to manifest His glory. James expresses our responsibility for this truth.

Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance. And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing. (James 1:2-4)"
