God will use you no matter how old you are.
Read: Luke 2:37-38
37 Then she lived as a widow to the age of eighty-four. She never left the Temple but stayed there day and night, worshiping God with fasting and prayer. 38 She came along just as Simeon was talking with Mary and Joseph, and she began praising God. She talked about the child to everyone who had been waiting expectantly for God to rescue Jerusalem.
