Infirmities are sometimes for bringing glory to God

Acts 3 - 4:4

Peter and John were going to a prayer meeting when a beggar,
who was being carried to the temple to beg, asked them for money.
Peter demanded that the beggar focus on them. The beggar expecting
money gave them his attention. Peter claimed that they did not have
riches but pulled the beggar to his feet and the beggar began to walk.
The beggar was jumping for joy, he was around 41 years old and lame
from birht..
People came running to see this man that had been crippled.
This gave Peter the opportunity to share the Gospel. He declared
that because of their sin they kill Jesus. Peter also showed them
that the patriarchs of old predicted this Jesus would come.
The people listening to this became convicted of their sin and
turned their life of to Jesus.
