12 Therefore, my dear friends, as you have always obeyed – not only in my presence, but now much more in my absence – continue to work out your salvation with fear and trembling, 13 for it is God who works in you to will and to act in order to fulfil his good purpose.
14 Do everything without grumbling or arguing, 15 so that you may become blameless and pure, ‘children of God without fault in a warped and crooked generation.’[a] Then you will shine among them like stars in the sky 16 as you hold firmly to the word of life. And then I will be able to boast on the day of Christ that I did not run or labour in vain. 17 But even if I am being poured out like a drink offering on the sacrifice and service coming from your faith, I am glad and rejoice with all of you. 18 So you too should be glad and rejoice with me.
Matthew 5: 13-16
Salt and light
13 ‘You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.
14 ‘You are the light of the world. A town built on a hill cannot be hidden.15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house.16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
