"Be very careful, then, how you live—not as unwise but as wise, making the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is. Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit. Speak to one another with psalms, hymns and spiritual songs. Sing and make music in your heart to the Lord, always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ" (Eph 5:15-20, NIV)The word translated 'opportunity' in this passage is kairos - a special moment in which the Spirit of God is looking at act through us. Paul is instructing us to walk around with our eyes open to what God is doing in the world, in our life, in the lives of others - and to respond by asking and doing what God would please God in that moment. This spirit-filled life is contrasted with a life on auto-pilot, never considered how God may be present or looking to act in the situations we're in. It's a very powerful passage - and a great opportunity for us to live according to the Spirit, and make the most of every opportunity in this New Year.
