Commentaries:
No man - by scholarship, human reason, or intelligence - can comprehend the whole truth of God apart from the Holy Spirit. Only by the intervention of the Spirit are we called to understand it. God, by divine revelation through the help of the Spirit, opens our minds to the "mysteries" of the truth, allowing us to discern what is truly vital to our salvation.

The Holy Spirit
God's Spirit imparts wisdom and understanding. It teaches His way of life, comforts, and helps us. Even when we cannot express ourselves in our prayers, the Spirit aids us in making our requests before God.

The Holy Spirit
For those who have made the New Covenant with God, it is the Holy Spirit that teaches and brings to remembrance—not the ceremonial law! Hebrews 10:3 shows that the sacrifices were only a reminder of sin. Today, the Holy Spirit is the reminder, triggering thoughts in our minds. In addition, because God has made the Spirit available, the various washings that are emblematic of God's Spirit are also set aside. Here are clear statements that the imposition of those ceremonial regulations has been lifted.
