Introduction:
The concept of God's rejection is a sobering theme found throughout the Bible, illustrating the consequences of disobedience, unbelief, and rebellion against God's will. This entry explores the biblical instances and theological implications of divine rejection, emphasizing the importance of faithfulness and obedience to God.

Old Testament Instances:

1. Cain's Offering:
In Genesis 4:3-5, Cain and Abel bring offerings to the Lord. Abel's offering is accepted, but Cain's is rejected. The text states, "but for Cain and his offering, He had no regard. So Cain became very angry, and his countenance fell" (Genesis 4:5). This rejection highlights the importance of offering to God with a sincere heart and in accordance with His standards.

2. Saul's Rejection as King:
King Saul's disobedience leads to his rejection by God. In 1 Samuel 15:26, Samuel tells Saul, "I will not return with you, because you have rejected the word of the LORD, and the LORD has rejected you as king over Israel" . Saul's failure to fully obey God's command demonstrates the serious consequences of partial obedience and self-reliance.

3. Israel's Rejection of God:
Throughout the Old Testament, Israel's repeated idolatry and rebellion result in God's rejection. In Hosea 4:6, God declares, "My people are destroyed for lack of knowledge. Because you have rejected knowledge, I also will reject you as My priests" . This passage underscores the importance of knowing and adhering to God's law.

New Testament Instances:

1. Rejection of Jesus:
The New Testament records the rejection of Jesus by many of His contemporaries. John 1:11 states, "He came to His own, and His own did not receive Him" . This rejection fulfills Old Testament prophecies and highlights the tragic reality of unbelief.

2. Warnings to the Churches:
In Revelation, Jesus warns the churches about the consequences of spiritual complacency and disobedience. To the church in Laodicea, He says, "So because you are lukewarm—neither hot nor cold—I am about to vomit you out of My mouth" (Revelation 3:16). This serves as a warning to maintain fervent faith and commitment.

Theological Implications:

1. Holiness and Obedience:
God's rejection is often linked to a failure to uphold His standards of holiness and obedience. Leviticus 26:14-15 warns, "But if you will not listen to Me and carry out all these commandments, and if you reject My statutes and despise My ordinances... I will do this to you" . This emphasizes the necessity of living in accordance with God's commands.

2. Faith and Acceptance:
While rejection is a reality for those who turn away from God, the Bible also offers hope for acceptance through faith. Romans 11:20-21 cautions, "Do not be arrogant, but be afraid. For if God did not spare the natural branches, He will not spare you either" . This passage encourages humility and faithfulness to remain in God's favor.

3. Repentance and Restoration:
Despite instances of rejection, the Bible consistently offers the possibility of repentance and restoration. 2 Chronicles 7:14 promises, "if My people who are called by My name humble themselves and pray and seek My face and turn from their wicked ways, then I will hear from heaven, forgive their sin, and heal their land" . This underscores God's mercy and willingness to restore those who return to Him with sincere hearts.

Conclusion:
The theme of God's rejection serves as a powerful reminder of the importance of faith, obedience, and repentance. It calls believers to examine their lives, ensuring alignment with God's will to avoid the consequences of divine rejection.
