Just like a child is expected to develop after birth so is a Christian expected to develop after the new birth.

QUESTION RECEIVED:

Does the fullness of God dwell in us when we accept Jesus Christ as Lord and Savior?

MY ANSWER:

Jesus told the disciples to receive the Holy Spirit in John 20.  At Pentecost Jews from all over the world received the Holy Spirit.

We are saved and declared righteous before God.

We start in holiness when we are saved.  We can grow in holiness and are expected to when saved.

Just as the people in the Old Testament feared seeing the living God or his holiness would overwhelm them.  Moses had to be shielded and could only see the train of God’s glory in Exodus 3.

Ephesians 3:19 (NASB95)

19and to know the love of Christ which surpasses knowledge, that you may be filled up to all the fullness of God.

Jesus had all and acted in all.   We don’t but we are set toward and grow in holiness..

Colossians 2:9

9 For in Him all the fullness of Deity dwells in bodily form,

Just like a child is expected to develop after birth so is a Christian expected to develop after the new birth.

God is fullness and complete and is all and more than we can ever need.

As wise preacher said we are cracked pots and need to be refilled.
When we worship individually and corporately I believe this is when it happens.
