John 14:16 And I will ask the Father, and he will give you another advocate to help you and be with you for ever
When Jesus explained He was not going to be with the disciples for much longer, He reassured them by saying He would ask God to bring someone who could be with them – always.
This being the third person in the God-Head. The Holy Spirit.
Whilst we cannot get our heads round this fact God is three separate parts, but one God – He does not want us to be left alone or confused by things.
Listen out for the Holy Spirit and He will give you enough understanding to live your life for God in faith!
