There's some risk in saying what I'm about to say. One, it could be taken as preachy or holier than thou. Two, it could appear prideful or suggestive of some belief of having arrived. I present this humbly and in awe of God's power, and not my own.
As a kid one of the worship songs frequently sang in our Church was "Turn Your Eyes Upon Jesus," written by Helen H. Lemmel in 1922. The refrain goes
Turn your eyes upon Jesus,
Look full in His wonderful face,
And the things of earth will grow strangely dim,
In the light of His Glory and Grace.
If you know me well you, might be scratching your head. I tend to feel very uncomfortable with this kind of flowery expression of love for God. Maybe it's my masculinity fighting against sentimentality.
More than the specific words, though, I am struck by how true the refrain is in my life. While I wouldn't express it the way that the song does, it captures it perfectly. The more I get to know God through studying the Bible, communing with Him through prayer, and sharing my thoughts with other believers, the less important the things of "the world" are.
This type of change can happen over a short period of time. Just a few months ago, I was focused on music and writing and whatever my (secular) hobbies and interests were. But God has turned my mind both inward (looking at my spirit) and upward (looking to Him.) I find myself losing interest in things that even weeks ago captured my imagination.
I will readily admit that this type of transformation, if you want to call it that, has taken place in my life in the past. In each instance, it has "worn off," as if it were a fad or trend. I suspect that my corrupted human heart and mind tries to flee from God -- rebel against Him! Hopefully that is not the case now.
Whatever the future holds I do not know. But I am certain that the more you focus on God the less important everything else will be to you.
