'Acknowledges' in the Bible

Whoever denies and repudiates the Son does not have the Father; the one who confesses and acknowledges the Son has the Father also.

By this you know and recognize the Spirit of God: every spirit that acknowledges and confesses [the fact] that Jesus Christ has [actually] come in the flesh [as a man] is from God [God is its source];

Whoever confesses and acknowledges that Jesus is the Son of God, God abides in him, and he in God.
