Paul says when he was a child he spoke like a child.  He was comparing tongues use to young church use.

Everyone is kind and nonjudgmental,  and would not like to criticize a practice adopted in other churches.  I believe that is about right.  Those who follow Christ must search for truth.  It's a requirement :

> **Luke 11:13 NET** If you then, although you are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!” 

Young churches are ministered to by God:

> **Luke 22:35 NET** Then Jesus said to them, “When I sent you out with no money bag, or traveler’s bag, or sandals, you didn’t lack anything, did you?” They replied, “Nothing.”

Jesus's faith provided teaching and supplies. The perfected church, the mature church will manifest it's own faith.  To reach maturity,  they must sell even their most precious possessions :

> **Luke 22:36 NET** He said to them, “But now, the one who has a money bag must take it, and likewise a traveler’s bag too. And the one who has no sword must sell his cloak and buy one.

Much sacrifice is involved in transmitting the word of God :

> **2 Corinthians 4:12 NET** As a result, death is at work in us, but life is at work in you.

> **John 15:13 NET** No one has greater love than this – that one lays down his life for his friends.

> **1 Corinthians 13:9-13 NET** For we know in part, and we prophesy in part, but when what is perfect comes, the partial will be set aside. When I was a child, I talked like a child, I thought like a child, I reasoned like a child. But when I became an adult, I set aside childish ways. For now we see in a mirror indirectly, but then we will see face to face. Now I know in part, but then I will know fully, just as I have been fully known. And now these three remain: faith, hope, and love. But the greatest of these is love.

> **John 14:12 NET** I tell you the solemn truth, the person who believes in me will perform the miraculous deeds that I am doing, and will perform greater deeds than these, because I am going to the Father.
