I'm certain that it is a combination of factors, missing my family, the opportunity to be silent and reflect on the flight, and the anticipation of the week of wonderful meetings, speaking and teaching engagements and the opportunities for the Gospel of Christ to take shape... In fact there are probably a whole lot more factors such a memories, aspirations, sights, sounds and many things I am not aware of!
Here's the point... God does something within me on these trips. I grow closer to Him. I begin to slow down and experience His heart for this beautiful world, for all it's people, for the animals and plants, the landscapes. God helps me to feel love, compassion, joy and sadness.
In my doctoral research I came to discover that identity is formed through a complex set of interactions that take place within the individual and the community. It is a bit like the triune God - the identity of the individual persons comes to the fore in their relationships with others.
As you empty yourself (what is known in traditional theology as 'kenosis') you grow to become who God desires you to be, a bearer of the loving, serving, courageous image of Jesus Christ (this concept is known in Eastern and Patristics theology as 'Theosis' - growing in the likeness and mind of Christ). Paul writes about kenosis and Theosis in Phil 2.2-6, culminating around verse 11 if I am not mistaken.
So, as I sit alone in Singapore airport, enjoying a cup of coffee, God is doing something within me. I pray that it is good, that I may be less like me and more like Christ.
Look at the beautiful orchids in this picture. A real highlight each time I fly via Singapore. Indeed, the earth is the Lord's and everything in it (Psalm 24)!
Please pray with me!
