5. Are these revelations sufficient to get to know God and His will fully?

No, there is a lot that is incomprehensible in nature and in the lives of many people. Our conscience can be wrong too. We need a better revelation to recognise God for who He really is.

• Who has known the mind of the LORD that he may instruct Him?” But we have the mind of Christ. (1 Corinthians 2:16)
• Truly You are God, who hide Yourself, o God of Israel, the Saviour! (Isaiah 45:15)
• For with You is the fountain of life; in Your light we see light. (Psalm 36:9)
