We are therefore lost. The passage v22-23. Paul is probably stating the fact that the people are religious. They are concerned about knowing God and willingly admit that they don't know everything about Him. God is defined.
Humanity is defined.
The human condition, sinfulness. We have worshipped and sought after the creature rather than the creator. God's demand and our response - repent. Judgement for those who fail to respond. The resurrection is the guarantee of this.
