Though the rejection of Christ was universal, individuals did respond personally—some believed him and accepted him as the Son of God, the Savior. To them he gave the right to become children of God. In Greek right means “authority or permission.” In this context, it speaks of God granting the right or giving the privilege for the new birth. No one can attain this new birth by his or her own power, merit, or ability. Only God can grant it. One is not in God’s family because he or she is a Jew by physical birth (or even born into a Christian family). The new birth cannot be attained by an act of human passion, and it has absolutely nothing to do with any human plan. It is a gift of God.
Many believed superficially in Jesus when they saw his miracles, but they did not believe in Jesus as the Son of God. They “believed” in him while he fulfilled their expectations of what the Messiah should be, but they left him when he defied their preconceived notions. We must believe in Jesus as Jesus, the Son of God; we must wholeheartedly believe in Jesus, not limiting him to our ideas and misconceptions; we must regard Jesus as the Bible truly presents him.
