John 14:26 – But the Comforter, which is the Holy Spirit, whom the Father will send in My Name, He shall teach you all things, and bring all things to to your remembrance, whatsoever I have said unto you.
II Peter 1:3 – According as His divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of Him that hath called us to glory and virtue:
Students attend school, they have a teacher who gives them books and teaches them out of those books, and the teacher gives her students homework.
The teacher gives them tests to see what they’ve learned.
This teacher has assistants.
The schoolhouse is the Church building.
The homework is our Bible study and prayer at home.
In prayer, we ask our Heavenly Father to help us understand what we are studying: and the Holy Spirit will give us the answer.
This book, the Bible, has many Books, It covers all things concerning life and godliness.
We are the students.
If we never open the Book or if we never go to school or Church we write our own book and make God whoever we want Him to be.
Like learning in school 2+2=4. That is correct math. This teacher (the Holy Spirit) says, Jesus is the Way, the Truth, and the Life, no man cometh to the Father but by Him (Jesus Christ). Jesus is grace and truth.
How do I have this knowledge? I learned it from the Teacher and His Book at Church and at home.
II Peter 3:18 – Grow in grace, and in the knowledge of our Lord and Savior Jesus Christ.
