Those who live only to satisfy their own sinful nature will harvest decay and death from that sinful nature. But those who live to please the Spirit will harvest everlasting life from the Spirit.
Galatians 6:8 NLT

How do we please the Spirit? By doing what the Holy Spirit says.

The Holy Spirit will always tell us to do something good (Gal. 6:9). He’ll tell us to encourage that random person sitting alone, He’ll tell us to buy something nice for our child’s teacher, He’ll tell us to spend more time with our parents, or He’ll tell us to give a certain amount to the Kingdom of God. Even if it doesn’t seem good at first, especially to our flesh, it will work out in our favor.

As we please the Spirit, we’ll have a harvest of everlasting life and in verse 9 it says we’ll reap a harvest of blessings. So, please the Spirit by following the leading and guiding of the Spirit.
