Show us the Father

"Jesus said to him, 'Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, show us the Father'?" John 14.9

Those who are on the Lord Jesus must, as a rule, exude His perfume, have His image and manifest His character. If someone claims to have the Holy Spirit but does not reflect the image of God, he deceives himself.

Where and when?

"Then you shall again discern between the righteous and the wicked, between one who serves God and one who does not serve Him." Malachi 3.18

The promise is crystal clear: you shall discern again. And who made this promise? The Lord of Hosts. Where and when should it be fulfilled? The only place where we could see this difference is right here on Earth, and it has to be now, considering that in the Kingdom of Heaven there will be no wicked people. 
Why the delay in the fulfillment of this promise? Because the surrender to the Lord has been slow.
The difference will only be seen when those who are faithful surrender body, soul and spirit in truth.

MANY BELIEVERS, VERY FEW CHRISTIANS

Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.       John 3.3-5

Only those who are born again can SEE the Kingdom of the Spirit of God.
Only those who are born of water and the Spirit can ENTER the Kingdom of the Spirit of God.
This is why many are believers; however, very few are Christians.

THEY WILL SEE GOD

"And you shall be holy to Me, for I the Lord am holy, and have separated you from the peoples, that you should be Mine."           Leviticus 20.26

In order for us to see the Lord we must be holy.
Holy means separated from unrighteousness and separated from sin.
How could the Holy of holies allow sin into His presence? Can Light and darkness be combined? How about Good and evil?
Those who want to see the Lord God must sacrifice their sins in order to come clean before His presence.

HEART

"Blessed are the pure in heart, for they shall see God."

Matthew 5:8

To be pure in heart means being sincere, having nothing to hide and free from grudges. Those are the ones who will see God.
