2 Timothy 4:1-5
1I charge you in the presence of God and of Christ Jesus who is to judge the living and the dead, and by his appearing and his kingdom: 2preach the word, be urgent in season and out of season, convince, rebuke, and exhort, be unfailing in patience and in teaching. 3For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own likings, 4and will turn away from listening to the truth and wander into myths. 5As for you, always be steady, endure suffering, do the work of an evangelist, fulfil your ministry.
Psalms 37:3-6, 30-31
3Trust in the LORD, and do good; so you will dwell in the land, and enjoy security. 4Take delight in the LORD, and he will give you the desires of your heart. 5Commit your way to the LORD; trust in him, and he will act. 6He will bring forth your vindication as the light, and your right as the noonday. 30The mouth of the righteous utters wisdom, and his tongue speaks justice. 31The law of his God is in his heart; his steps do not slip.
13"You are the salt of the earth; but if salt has lost its taste, how shall its saltness be restored? It is no longer good for anything except to be thrown out and trodden under foot by men. 14"You are the light of the world. A city set on a hill cannot be hid. 15Nor do men light a lamp and put it under a bushel, but on a stand, and it gives light to all in the house. 16Let your light so shine before men, that they may see your good works and give glory to your Father who is in heaven.
