It is not only important to honour God but crucial. Viewed from the standpoint that God is Spirit (Consciousness), then there is nothing else. Scriptures teaches us that we are made in the image of God (Spirit), that He dwells in us, and that we are not our own. It follows that in the same way that we feed the 'material, the consumer world', so too should the world of Spirit be fed. They go hand in hand.
'The Earth is the Lord's and its fullness thereof', says the Christian scriptures. So there is nothing here that we can call our own. Everything belongs to 'our Father', as the Christ puts it in Our Lord's Prayer.
What does it mean to honour God? St. Paul exhorts us to be imitators of Christ, that is to say, practice His works. Be an exemplary example to others. Speaking in Discipleship, David Watson, in the last four lines of his poem, says:
"And from your eyes He beckons me,
And from your heart His love is shed.
Till I lose sight of you, and see
The Christ instead". (Hodder and Stoughton Ltd)
We came here to glorify God, to do the Will of the Father in Heaven. We are the Temple or instruments of Spirit, and as such must do the work as would exhalt the Spirit. 'Watch and Pray', says the Scriptures, and again, 'let our work so shine that it may glorify our Father in Heaven'.
Various God-men, seers, sages and saints have demonstrated this throughout the ages. Indeed that's why they came. To create a beacon so that we could see a way to follow. I like answer 90 by Moonlightened. Let us have many windows in an expansive Heart. 'Contraction is death, expansion is life, says the Swami Vivikananda. Let us all strive to live expansive and compassionate hearts. Be ever vigilante. Watch and pray with intense Faith. Serve ceaselessly, and the God we honour will certainly come to our aid.
