1. Which one is the greatest between gift of the Spirit and fruit of the Spirit? Which one is the greatest?

2. Is it proper to go to church and you are told to lead prayer and when you started, you spoke in tongue from the beginning to the end. As in is it good to lead a church prayer only in tongues

3. What's the difference between wisdom, knowledge and prophecy. 1cor 12 vs 4 - 11.

God bless you

When people claim to be speaking in tongue.....

1. Which one is the greatest between gift of the Spirit and fruit of the Spirit? Which one is the greatest?

There is no hierarchy in the gift of the Spirit (i.e. there is no the smallest or greatest) because they are given for the common good.

As for the fruit of the Spirit, what out lasts all is love, so love is the greatest of the fruit of the Spirit
Love is rendered 7 ways in Greek, the love which is the greatest mentioned in Galatians 5:22 is the Agape love; love that's is given unconditionally

It isn't good at all, the reason is because you or no one else interpreting those present would not know when at each prayer points to agree with you in saying amen.

Also why would you have the need to pray in a language and make matters worse, without interpretations, when others present don't understand diddly squat what's being said?

Wisdom has to do with decision(s).
When a right or good decision is made, you've applied wisdom and deemed wise.
If the outcome or conclusion of a matter, ends up with a wrong or bad decision being made, then folly is said to have been applied and the person doing such is deemed foolish or called a fool.

Knowledge is information.
This can be acquired mentally or be known experientially

Prophecy is fore-knowledge, as in knowledge or information known before hand.
It's an advance knowledge of eventq
