The people God calls are the people who leave a lot of room for God to work. They think little of themselves but they can't stop thinking about Jesus! They pray their hearts out for those who are serving the Lord in ministry and seek God's blessing of strength and boldness on them. They delight in knowing others have been used of God to bring the lost to Christ and they are the ones who are ready to add these new believers to their prayer lists. They make sure a place is ready for meetings to be held and they are the ones who stay after the service to help with the cleanup. They humbly offer themselves for menial tasks and step aside for those who have the "important work" that needs to be done. And they do this without looking for a "thank you" or any recognition. They just want to please the Lord.
They are the ones who give their "two mites" when that's all they have to give. They are the ones who don't just stop at "going the 2nd mile." They're willing to keep going until they drop. They're idea of success is praising God for the achievements others have made for His Glory. They can't imagine they've done anything to be proud about. They just want to please the Lord.
