We reap what we sow and we shouldn't grow weary in doing good. Paul ends Galatians on a strong note

In the entire Book of Galatians we have seen Paul battling those who wanted to add
something other than Jesus to their salvation. We learned in Chapter 5 that we are to live by
the Spirit. I called it “walking by the Spirit” in the sermon. Basically, we have a tug-o-war going
on within us. The old sin nature we were born with pulls us to live according to our fleshly
desires while the Holy Spirit which came into us at salvation pulls us towards thinking, acting,
speaking, and behaving in accordance with God’s desire for our lives. As the Holy Spirit lives
within us, we literally have God’s law written into our hearts.

Lets not grow weary
