Be Fruitful

In the Old Testament, there are several times when the Lord tells someone,

 "...be fruitful and multiply..."

I have always just equated this phrase to having a family. 

But, in the New Testament it says,

"...the fruit of the Spirit is love, joy, peace, long suffering, gentleness, goodness, faith,
Meekness, temperance."

Now, being fruitful to me means to seek for these things of the Spirit and spread them throughout the world.
