You can say that all you want.
But if your argument is that what we sing is not in conversation with God, then your theology of worship is severely impoverished.
The entire Divine Liturgy is a conversation. God speaks to us, and we respond. That's what the Liturgy is, that's what Christian worship is. This is our RELATIONSHIP with God. God speaks to us, we speak to God, we confess together as God's people and children, we delight in Christ our Lord who has reconciled us to the Father, and we share in the life of God through the Holy Spirit which we have received in Christ God's Son, in which we are sons and daughters of God--and we are here together, with the holy angels and the entire host of heaven in shared communion to declare the praises of our God, to declare thanksgiving to our God, and to share in, delight in, and enjoy God--"Thy kingdom come. Thy will be done on earth as it is in heaven". As we join with the heavens, as heaven and earth meet together, and God is in our midst--all in anticipation and echoing the future Glory of when that Good Day comes and God makes all things new, new heavens and new earth, and God will be all in all. The Marriage Supper of the Lamb. Hallelujah!
