Words of knowledge are given to unlock situations and to uncover sin, or the cause of problems. They can also build faith and pave the way for other gifts (such as prophecy)

If knowledge is having lots of information in your brain then wisdom is knowing what to do with it.
The Holy Spirit can give us the ability to interpret and utilise the knowledge we have, way beyond any human ability.

The Gifts are exactly that - Gifts. We cannot earn them and God will not withdraw them

There are two reasons why this phrase is placed at the end of the list of the Fruit of the Spirit:

1) How could any law be offended by such godly qualities
2) Living according to the fruit of the Spirit puts us in harmony with God's Law

Self-control is the ability to live on purpose instead of being driven by every whim or temptation that comes our way.
Jesus gave us a brilliant example of the power of self-control when He was tempted by Satan in the wilderness.

Gentleness is the ability to apply strength on a way that causes no harm and no fear.
Gentleness sis not the expression of weakness. It is the Godly application of the strengths He has given us

Faithfulness is very dear to God's heart and He values it in us.

The Holy Spirit will help us remain true to our relationships, our purpose, our friends and our God

Id kindness is behaving in a way that is pleasing to other people then goodness is living in a way that please God and gives glory to him.

Kindness is the basis of the golden rule of civilisation - Do unto others as you would have them do to you.

Jesus was a brilliant example of kindness and we are commanded to be like him.
Fortunately the Holy Spirit can work through God's Word and out circumstances to build kindness in our hearts.

The patience that is a fruit of the Spirit enables us to use God's watch - not our own.
Patience keeps us in our circumstances long enough for God to do whatHe wants to through us and in us.
