Like a physical body that has many parts and functions, the Body of Christ also has the same. We are a member of it, and each of us has its own use. God created us physically so that we can be a part of His spiritual body, too. How can we make use of our functions and abilities for Him?
Each of us individually has a gift given by God to use all for His glory. If we can prophesy or can speak a new message from God to His people, we should do it according to the amount of faith we have. If we can serve others, we should serve. If we can teach, we should teach. If we can encourage others, we should encourage them. If we can give, we should be generous. If we are leaders, we should do our best. If we are good to others, we should do it cheerfully (Rom. 12:6-8)
Let us be united for the glory of God by using our own gifts. Remember that we are one in Christ. Do not waste your gifts, make use of it. You have a function, you are not useless.
