Romans 8:14 For all who are led by the Spirit of God are sons of God.
There are two types of people in this world. There are those who are led by the Holy Spirit and there are those who are lost. There are no other options. When left to our own wisdom to guide ourselves, we get nowhere. Only by the Holy Spirit can we talk in the way God has for us.
To some, this may seem a ridiculous notion, pointing to the achievements of secular mankind who has not consulted God or been Spirit-led in their discoveries throughout the ages. It is an interesting observation, however, those who think that mankind has the potential to know all there is to know, thus disproving the existence of God, are disregarding the fact that God created all there is to discover. The achievements of man are of no eternal consequence.
But those led by the Spirit are children of God, adopted into His family. We have been the recipients of the greatest gift of all time: God himself. There is nothing of greater eternal significance. It doesn’t matter what we accomplish in this temporary life in regards to greatness because true greatness is only found in one place. It is God’s to give.
