What an awesome invitation from the Lord! He's inviting you to ask Him for the salvation of the souls of men in your world (your neighborhood, workplace, etc.). God wants to give you the souls of men, so you can fill them with the Word, nurture them in the way of righteousness and teach them how to live the Christ-life! However, you'd have to ask in intercession. Pray for the lost that they may receive salvation.
In Matthew 28:19-20, Jesus said, "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you...." That's the charge given to us. You therefore have a God-ordained right to ask for the souls of men; and when you ask, receive, because the Word has already been given that He who asked shall be given (Matthew 7:7).
If you're a cell-group leader, a fellowship coordinator or even a Pastor, practise this. Take the limits off and be bold to say, "Blessed Father, in the Name of the Lord Jesus, I receive so-and-so number of souls into this fellowship, with the ability to retain and nurture them in the way of righteousness". When you do, the Lord will give you visions and ideas, on how and what to do to make it happen.
It's time to lay claims to the souls of the unsaved in your world. It doesn't matter where you function. He said, "Ask and I will do it!" So, act on the Word and ask. Don't ask and say, "I'm waiting on God to do it; no. When you ask, believe it's done, and act accordingly! You'll see results. Halleluiah!
