You have hidden these things from the wise and prudent and have revealed them to babes

Matthew 11:25
At that time Jesus answered and said, “I thank You, Father, Lord of heaven and earth, that You have hidden these things from the wise and prudent and have revealed them to babes.

One of these truths that are hidden from the wise and prudent is that the relationship with God is attained by obedience alone. It is not something that can be attained by lots of study, thinking and being careful or doing the right things. It is an instant that we decide to obey, then we walk in the light with God. The moment we disobey, we step out of obedience and walk in darkness.
