What we do for God we also do for ourselves

"We must love and seek God, not for ourselves but for him, like
sons or daughters who find all their joy in taking part in their
father and mother’s activities.
When Jesus taught us to pray using the words ‘Our Father in
heaven, hallowed be your name. Your kingdom come, your will be
done on earth as it is in heaven’, he gave us precisely the
programme we have to achieve. We must sanctify the name of God
within, draw heaven down into ourselves and do his will, as the
angels in heaven do. What we do for God we also do for ourselves,
since we are in him and he is in us."
