verse 26

John 14:26 “But the Helper,  the Holy Spirit,  whom the Father will send in My name,  He will teach you all things,  and bring to your remembrance all that I said to you.”

The Holy Spirit would teach what God the Father wanted the disciples to know. Then, The Holy Spirit helped the disciples remember as they wrote down what they witnessed.

The most important witness is God the Holy Spirit. If you love Jesus, the Holy Spirit will teach you and help you remember too.

Prayer coaching.  Holy Spirit, teach me all the things You want me to know, and remind me of what You have shown me.
