We are chosen for this task
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.
1 Peter 2:9 (ESV)
We have Holy Ghost power
His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence,
2 Peter 1:3 (ESV)
We grow when each one does his or her part
From whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.
Ephesians 4:16 (ESV)
