1 Chronicles 11:1-4 is a biblical text about the story of Rehoboam and Jeroboam where the christians could learn about the causes and impact of church split.

1 Chronicles 11:1-4 (NIV) reads: "All Israel came together to David at Hebron and said, 'We are your own flesh and blood. In the past, even while Saul was king, you were the one who led Israel on their military campaigns. And the Lord your God said to you, 'You will shepherd my people Israel, and you will become their ruler.' When all the elders of Israel had come to King David at Hebron, he made a covenant with them at Hebron before the Lord, and they anointed David king over Israel, as the Lord had promised through Samuel."

This passage highlights the unity of all of Israel coming together to anoint David as their king. However, it also foreshadows the division that would eventually come between the Israelites, leading to the split between the northern kingdom (Israel) and the southern kingdom (Judah) under Rehoboam and Jeroboam.

The causes of this split can be attributed to various factors, such as political power struggles, religious differences, and social injustices. Ultimately, the kingdom split into two, leading to division among God's people.

The impact of this division was significant, as it weakened the overall strength of the Israelites and left them vulnerable to outside attacks. It also led to a decline in spiritual unity and cohesion among the people, making it harder for them to stand united in their faith.

Christians can learn from this passage about the importance of unity within the church and the need to work towards reconciliation and peace in the face of disagreements and divisions. It serves as a reminder to prioritize the teachings of Jesus and to strive for harmony and understanding among believers, even in times of conflict.
