Usain Bolt said:
“Follow me on twitter”
and he wants to make himself to a legend.
“Follow my example, as I follow the example of Christ”
(1. Corinthians 11:1)
and, after 2000 years he is still known all over the world.
I prefer what Paul said:
“But, Let him who boasts boast in the Lord.
For it is not the one who commends himself
who is approved,
but the one whom the Lord commends”
(2. Corinthian 10:17-18)
