1 Corinthians 15:33
Do not be deceived: “Bad company ruins good morals.”
You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet. You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.
Iron sharpens iron, and one man sharpens another.
Whoever walks with the wise becomes wise, but the companion of fools will suffer harm.
1 Peter 3:16
Having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame.
You were running well. Who hindered you from obeying the truth? This persuasion is not from him who calls you. A little leaven leavens the whole lump.
1 Peter 3:15
But in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect,
1 Peter 2:12
Keep your conduct among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.
2 Timothy 3:16-17
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work.
Give instruction to a wise man, and he will be still wiser; teach a righteous man, and he will increase in learning.
Whoever heeds instruction is on the path to life, but he who rejects reproof leads others astray.
A soft answer turns away wrath, but a harsh word stirs up anger.
Make no friendship with a man given to anger, nor go with a wrathful man,
Many seek the favor of a generous man, and everyone is a friend to a man who gives gifts.
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
1 Timothy 4:12
Let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity.
In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.
1 Corinthians 5:6
Your boasting is not good. Do you not know that a little leaven leavens the whole lump?
And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.
1 Peter 2:9
But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.
