The emphasis on Christ's earthly ministry is misleading by trying to mix the Gospel of the Kingdom (under the Law) with the Gospel of Grace (as revealed to the Apostle Paul by the ascended Lord.)

He was sent only to the lost sheep of Israel to fulfill the covenant promises and prophesies, as their King when He rules and reigns a thousand years on David's throne on Mt. Zion in Jerusalem, on earth, occupied by the remnant who survive the great Tribulation.

Contrast that with the teachings of Paul, who following the risen Christ, is sent to the Gentiles and Jews to preach the finished work of the cross for salvation through faith alone in His atoning blood. Believers are baptized by the Holy Spirit into His Church, which is His Body, of whom He is the Head. Our citizenship is in heaven, where we will join Him in the air before the time of Jacob's trouble, to be with Him at His Second Coming.

Once one rightly divides the Word of Truth, separating what was intended for the Nation of Israel from that meant for the Church Age, all apparent contradictions are no longer an issue.
