Jesus said “follow me and I will make you fishers of men”. We have been called out of darkness into the light to be a light in darkness. When you feel led to minister to anyone, just do it. When you take that first step, God will direct your next step.
Luke 9:1-2 NASB
And He called the twelve together, and gave them power and authority over all the demons and to heal diseases.  And He sent them out to proclaim the kingdom of God and to perform healing.
