God’s Word says in 1 Peter 4:10 “As each one has received a special gift employ it in serving one another as good stewards of the manifold grace of God.” This puts the matter very simply. We all have been given gifts from God that we are to use in serving one another. The purpose of the linked inventory survey is to help you determine what some of your spiritual gifts may be.
The exercise asks you to respond to 160 statements based on your interest and experience in certain gifts. Do not respond on the basis of what you think you ought to say. Rather, respond to what interests you. Don’t let modesty hinder you from agreeing with statements that are true of your abilities.
