Mission vs. Distraction

"And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ;" Ephesians 4:11-12 (NAS)
God has a purpose for your life.  He may have a series of short term jobs for you to do, a lifelong occupation in store for you, or both.  His objective for you is both His glory and your fulfillment.
As surely as there is a mission for your life, there is a plethora of distractions to draw your attention away from your mission.  Some distractions are unmistakable: obvious time-wasters or blatantly wrong activities.  But often, distractions come camouflaged as good causes, and diligence is required to discern between your mission and a diversion.  "All things are lawful, but not all things are profitable.  All things are lawful, but not all things edify."  1 Corinthians 10:23 (NAS)
It's your responsibility to find out what God's specific plan for you is.  Read the Bible, pray (this means listening to God as well as talking to Him), and spend time with His people.  The Lord often sends individuals to speak His truth into your life and help you get your bearings.
"Your ears will hear a voice behind you, 'This is the way, walk in it,' whenever you turn to the right or to the left."  Isaiah 30:21 (NAS)
If you're struggling to differentiate your mission from a distraction, start basic.  Is Jesus reaching the people you live with through you?  Are you representing Christ at work?  Do you have respect for the barista, the cashier, the server at the restaurant, the customer service rep?  Does your everyday life reflect God at work in you?
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age."  Matthew 28:19-20 (NAS)
