The true church of Christ is built on the foundation of Jesus Christ. There are many who call themselves part of the church, yet they have laid a foundation of ideology, humanitarianism, social justice, or an imaginary Jesus of their own making. These are not part of Christ's church, since they have laid a false foundation of "sand" which will crumble. The only valid foundation for any church must be the Jesus Christ of the Bible, God come in the flesh, born of a virgin, perfectly sinless in his human existence, crucified on the cross for our sins, dead and buried in a tomb, resurrected bodily the third day, ascended to His Father in heaven and now sitting on the right hand of God. That Jesus alone is the foundation of the church, of Christianity, and the One in whom we must believe for salvation.
