"Encourage the exhausted and slack of hands, and strengthen the feeble. 

Say to those with anxious heart, "Take courage, fear not. 

Behold your God will come with vengeance, the recompense of God will come, but He will save you." Is. 35:3-4

We must broaden our understanding of evangelism: we evangelize when we help the weak in faith stand; when we restore the struggling Christian and encourage the doubting brethren.
