From a post off the Think Eternity blog that really touched me a while back:

"Still, there is a nagging sense, that there is no way we could ever keep up with all that needs to be done. Instead, we should seek to simply bless others using the spiritual gifts we are given by the Holy Spirit, and blow freely with the wind of Holy Spirit.

1. Bless others with our spiritual gift
Scripture shows in 1 Corinthians 12, that each of us is given at least one spiritual gift. It benefits all of us, when each of us discovers our gift and grows in our ability to use this gift to serve and help the rest. The purpose of our gifts are to serve one another. Peter says, "each one should use whatever gift he has received to serve others, faithfully administering God's grace in its various forms." (1 Peter 4:10, NIV).

2. Blow with the wind of the Holy Spirit
Scriptures says "The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit." (John 3:8, ESV). It is not up to us to decide when and where we will work best. Our duty is to remain dependent on the leading of the Lord, following Him with all our hearts and going where we sense He is placing us, with the incredible joy He gives."
