Call to ministry is not by merit but by divine gifting.
God calls men and women into ministry to make them serve as gifts to their generations. Ephesians 4:8-12
Those called into ministry are embodiments of gifts or gift personified for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ.
Everyone gifted will be required to render account of their stewardship someday – Matthew 25:14-30; Luke 16:2; Romans 14:12; Hebrews 13:17
For this reason, we are expected to render our services dutifully and faithfully. 1 Corinthians 4:1,2
