The Spirit searches all things, even the deep things of God. For who knows a person’s thoughts except their own spirit within them? In the same way no one knows the thoughts of God except the Spirit of God.
To conclude, the concept of the Trinity — the proposition that God, though being one in essence, is comprised of three divine persons — is thoroughly grounded in Scripture. The Bible attests to the complete and perfect deity of the Father, Son and Holy Spirit. Though the Father, Son and Spirit are distinct and non-synonymous, the doctrine does not violate the law of non-contradiction since theology concerning the Trinity maintains that God is one in a sense and three in a different sense. Christians can thus confidently assert and defend the Triune nature of God, a doctrine extremely unlikely to have arisen as a human invention in the context of monotheistic Judaism.
