As I meditated on this passage, I saw how different our perspective and selfish inclination is (The Flesh) than what God desires. When we focus on ourselves, our tendency is towards gratifying the desires of our flesh, and this is where we get in trouble. When our thoughts are all about 'me' we lose our ability to see things from God's perspective. As Paul writes - they are contrary to one another. I must learn to embrace the perspective John the Baptist had - I must decrease and He (God) must increase. We must learn to look to God's Spirit for correct perspective, leaving our self-focused ways behind.
Lord help me to live by Your Spirit - changing my focus and thoughts on what You say is important, rather than what I think is important.
