Telling people about Jesus Christ may be a nuisance, but if we do not tell them, the Lord will hold us accountable for our silence. For reasons known only to the Lord, He has ordained that the Good News of Salvation be declared by human beings, to other human beings. God did not proclaim the Gospel by Angels or by supernatural means. He has left the responsibility for the eternal souls of people, to us.
Saving people is not our responsibility, but telling them about how they can find forgiveness of their sins and eternal life, is our job.
Jesus, in a manner of speaking said: “You catch then, I will clean them”.
If we humbly and lovingly tell those whom we come in contact with that God is ready to forgive their sins and grant eternal life to all who come to God in Jesus name, then we have done all that He requires. If we are afraid and fear what they might say to us, or how they would react when we share the Lord with them, then they may be lost for our lack of courage.
