Become servants…

If we have become servants of him who redeemed us, we look to him who rules over us; no longer do we live for ourselves but for him who acquired us when he exchanged his life (1Cor 6.20). No longer are we masters of ourselves but he who purchased us is the Lord of his own possessions and we are his own property.Therefore, the law of our life is his governing will.
–Saint Gregory of Nyssa (c. 335 – c. 395)

God does not…

God does not have parts but is present totally everywhere, and consequently, since he is wholly in whatever belongs to him, he does not want only a part of you…Do you want to have everything? Give all of yourself and he will give you all of himself, and thus, not having anything of yourself, you will totally possess God and yourself in him.
–Saint Anthony of Padua (1195-1231)
