When we hear the word "spirit" it is impossible for us to conceive of something whose nature can be circumscribed or is subject to change or variation, or is like a creature in any way

Instead, we are compelled to direct our thoughts on high, and to think of an intelligent being, boundless in power, of unlimited greatness, generous in goodness, whom time cannot measure.

All things thirsting for holiness turn to Him; everything living in virtue never turns away from Him. He waters them with His life-giving breath and helps them reach their proper fulfillment.

He perfects all other things, and Himself lacks nothing; He gives life to all things, and is never depleted. He does not increase by additions, but is always complete, self-established, and present everywhere.

He is the source of sanctification, spiritual light, who gives illumination to everyone using His powers to search for the truth – and the illumination He gives is Himself.

His nature is unapproachable; only through His goodness are we able to draw near it. He fills all things with His power, but only those who are worthy may share it. He distributes His energy in proportion to the faith of the recipient, not confining it to a single share.

He is simple in being; His powers are manifold: they are wholly present everywhere and in everything. He is distributed but does not change. He is shared, yet remains whole.

St Basil the Great, On the Holy Spirit, 22

The principle of unity in our lives is quite simply God's will, transforming our will into his own. This is the answer to the problem, so vexed in all the manuals of spirituality, how to combine love of God with love of neighbour. The problem is illusory. The fundamental thing is not my love at all, but God's love.

My love for God is a function of his own divine love; my love for other people is a function of his love for them. "The love of me,' as the Lord said to St Catherine, 'and the love of your neighbour are one and the same thing, and to the extent that the soul loves me, it loves him too, because its love towards him emanates from me.'"

In everything it is God who works in us 'both to will and to work' (Philippians 2:13). So, just as in prayer we must seek to pray the prayers that God gives us, so in action we must seek to do the good works that God has prepared for us to walk in' (Ephesians 2:10). This is the love that validates our prayer and our activities; it is not a matter of our motivation, but of the reality of Jesus Christ, who is the Will of the Father.
