"As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God." I Peter 4:10 (NKJV)
"For as we have many members in one body, but all the members do not have the same function, so we, being many, are one body in Christ, and individually members of one another. Having then gifts differing according to the grace that is given to us, let us use them: if prophecy, let us prophesy in proportion to our faith; or ministry, let us use it in our ministering; he who teaches, in teaching; he who exhorts, in exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness."
Romans 12:4-8 (NKJV)
"And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ;" Ephesians 4:11-13 (NKJV)
One of your purposes in God's Orchestra is to edify, or build one another up, through the use of your instrument with your gifts. If you don't use yours, why not? Is there an area where you can serve? Can you pray about how/where to serve? Look around at the ministries in your local church, where can your gifts best be utilized.
Do you know what your gifts are? The Lord invites you to call upon Him.
"Call to Me, and I will answer you, and show you great and mighty things, which you do not know." Jeremiah 33:3 (NKJV)
He encourages His children to ask for good gifts.
“Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. Or what man is there among you who, if his son asks for bread, will give him a stone? Or if he asks for a fish, will he give him a serpent? If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask Him! Therefore, whatever you want men to do to you, do also to them, for this is the Law and the Prophets."
Matthew 7:7-12 (NKJV).
When you know your gifts and how to use your instrument to edify one another, you are able to show Christ-likeness to one another.
"for it is God who works in you both to will and to do for His good pleasure." Philippians 2:13 (NKJV)
And as a church, we will see the reality of God's word, "For nothing is impossible with God." Luke 1:27 (NKJV)
Once you see Him at work through you, the way you work for the Kingdom will never be the same.
"And whatever you do, do it heartily, as to the Lord and not to men, knowing that from the Lord you will receive the reward of the inheritance; for you serve the Lord Christ."
Colossians 3:23-24 (NKJV)
