Knowing God's will is crucial. "Whoever does God's will is my brother and sister and mother," Jesus stated, referring to those who know and do the Father's will (Mark 3:35). The chief priests and elders are rebuked by Jesus in the parable of the two sons for failing to accomplish the Father's will; especially, they "did not repent and believe" (Matthew 21:32). At its most basic level, God's will is for us to repent of our sins and place our faith in Christ.
