Impact: Being Salt & Light

Matthew 5:13 NLT

When salt loses its saltiness, it also loses its impact and necessity. 

Matthew 5:13 MSG- "Let me tell you why you are here. You're here to be salt-seasoning that brings out God-flavors of this earth. If you lose your saltiness, how will people taste godliness? You've lost your usefulness and will end up in the garbage."

Matthew 5:14-15 NLT

Stop hiding your light (impact). 

Matthew 5:14-15 MSG- "You're here to be light, bringing out the God-colors in the world. God is not a secret to be kept. We're public with this, as public as a city on a hill. If I make you light-bearers, you don't think I'm going to hide you under a bucket, do you? I'm putting you on a light stand. Now that I've put you there on a hilltop, on a light stand- shine!"
