Therefore, holy brothers and sisters, who share in the heavenly calling, fix your thoughts on Jesus, whom we acknowledge as our apostle and high priest. He was faithful to the one who appointed him, just as Moses was faithful in all God’s house. Hebrews 3:1,2
But now your kingdom will not endure; the LORD has sought out a man after his own heart and appointed him ruler of his people, because you have not kept the LORD’s command.” 1 Samuel 13:14
[Jesus said] “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over.” Matthew 18:15
