All over the world there are Christians who have lost their passion for God. It's amazing that it is possible to lose passion for the God who is described in the Bible, considering how massive he is, how awesome he is, and what he promises those who live for him, not only in this life, but for all eternity, but yet it happens. It has happened to me. Many times, my passion seems to waiver... and I don't 'feel it' like I used to. It's in these times that I really need to examine my heart, and check in if I am really living FOR Jesus or just wearing his name tag - "CHRISTIAN"... There are two reasons for sure followers of Jesus could lose their passion:
1) they simply step out of the will of God.
James 1:16-17 puts it this way - 16 So don't be mislead, my dear brothers and sisters. 17 Whatever is good and perfect comes down to us from God our Father, who created all the lights in the heavens.
For real, everything from God is GOOD! It then goes without saying that everything NOT from God; i.e. sin; is NOT GOOD. In fact it is harmful. And when a believer starts down a path of sin, it is not hard to lose passion for a holy God, who won't tolerate sin in His presence. He will cleanse us from if we are willing and obedient and desire to be close to him, but we can't chill with sin and then just mosey on down to God and sit on his couch like 'it's all good'... it isn't.
2) when we fail to apply God's word to our lives.
I was reading today in 'Life Application Study Bible' - and I decided to read the introduction before Genesis and see what it had to say. One paragraph I read was especially VERY good, and I wanted to share it with you:
"Application is putting into practice what we already know (see Mark 4:24 and Hebrews 5:14) and answering the question, "So what?" by confronting us with the right questions and motivating us to take action (see 1 John 2:5,6 and James 2:17). Application is deeply personal--unique for each individual. It is making a relevant truth a personal truth, and involves developing a strategy and action plan to live your life in harmony with the Bible."
So when we fail to actually apply God's word to our lives, whether we hear it through a teaching, a song, or reading the word, or even a book - no change happens. Truth is meant to change us! Not just to hear it and say, 'yeah that's truth', or 'that's a good word'... but to actually to live it out. That's the hard part.
God is moving. And if we don't move with him, in his will, and applying the truth he shows us - which is called 'obedience'... maintaining passion is, well, not going to happen. We can only be passionate about someone we are in constant relationship with.
