The definition of these words is unclear unless based on the Biblical definitions, not modern dictionaries. To understand them well we must uncover the meaning in the original Greek and to the culture of the time. We can become callused to it. But the Holy Spirit has much to say about this first of all fruits. If we will listen, He will show us things we never knew before.
Love is the all encompassing fruit.
As we progress in these studies, notice how the definition and connotation of each fruit begins to sound very similar to love. All the other fruits are different aspects, or expressions of love. Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. And the second is like unto it, Thou shalt love thy neighbour as thyself. But this is plainly not correct.
