God's life is the Father and Son blissfully existing (abiding together) in infinite Love.
The life of God is the love God has (experiences) eternally as the Father and Son affectionately behold and enjoy the infinite glory, beauty and worth of the other in, through and by the Spirit.
This is referred to as the beatific vision.
The life, love and Spirit of God go hand in hand.
Wherever the life of God is present so is the love and Spirit of God and
Wherever the love of God is present so is the Spirit and life of God and
Wherever the Spirit of God is present so is the life and love of God.
God is love 1 John 4:8
God is life 1Jn 5:20 John 14:6-9
God is Spirit John 4:24
The life of God is the dynamic of God that moves him to action.
The love of God is the holy affection that God has within his being.
The Spirit of God is that distinct being that consists of God's life and love.
Everything regarding the Spirit has to do with affections (emotion e.g. passion, love and joy) that moves him to action (willing, choosing).
The essence of God's being is Glory Beauty and worth.
Walking in the Spirit is our believing this very same love that God has for and within himself is fully ours (in and through Christ); receiving, participating in and expressing this love back to God first and then out to our fellow image bearers (other God like beings) thereby bringing him honor in displaying his glory beauty and worth to others.
When we come into God's presence via his Spirit we are made fully alive. Why? Because our life consists of being valued/loved (just as God's does). When we are in God's presence we experience the greatest sense of love/our value because He is most lovely and valuable. We are able enter into and enjoy this overflowing God of love, joy and bliss because we made to i.e. in his image.
