1 Corinthians 2:10 But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God.
It is not only the earth and nature that God opens our eyes and minds to; it is also His word and His will which He opens to us.
We can try all we want to be able to understand what has been written by people from the past, but unless we have some insight into their works, we will struggle to understand things properly.
God has given us the Holy Spirit to give us that guidance and support we need to grow with Him in this unfathomable world!
It is God, through His Spirit that opens our hearts to His world.
