John 1:23 John replied in the words of Isaiah the prophet, ‘I am the voice of one calling in the wilderness, “Make straight the way for the Lord.”’
Being able to show others that we are who we are because God has deemed it so or possible has got to be the only honest answer we can give. If we try to build ourselves up into something we are not we fool ourselves alone.
If we talk as if we are nothing, we make out God to be a liar. We are His creation and a temple for the Holy Spirit. If that is not enough to get you started then you have to start thinking again!
Get out there and obey God. He has already asked you to go… What are you waiting for?
