Do not marvel, my brethren, if the world hates you. (1 John 3:13, NKJV)
Jesus had told His apostles to expect the hatred of the world (John 15:19). The world loves its own, and hates the light that exposes its sins (Jno. 3:19-20). This comes as no surprise. Jesus is the light of the world; therefore, the world hates Him (and His Father) most of all (Jno. 15:18, 23-25). When we become Christians, we leave the dark world of sin to live as “children of light” and to walk in the light of truth (Eph. 5:8; 1 Jno. 1:6-7). Therefore, the world hates us, too. Note the irony. Jesus was not hated because He was a great sinner (“Which of you convicts Me of sin?,” Jno. 8:46; 1 Pet. 2:22). He was hated “without a cause” (Jno. 15:25). When people in the religious error and moral corruption of the world hate you for following Jesus and His truth, accept your cross and bear it for His sake (Lk. 9:23). Do not marvel. Their hatred is par for the course. Do not be distracted by the world from practicing righteousness and loving one another (1 Jno. 3:10-15).
