Titus 2:1 amp

But (as for) you, teach what is fitting and becoming to sound (wholesome) doctrine (the character and right living that identify true Christians).

As we represent Christ in our daily walk, we should make others want to emulate us for what we have.  We should seek peace and understanding in our relationships.  We should love each other as God loves us and have a humble heart.  The bible should be the basis for our lives and our families.  When we have all of this, then our light has Christians will shine.
