1 Timothy 1:16 Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting. 17 Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
That is what invisible means in scripture as meaning "not presently seen".
So being in the image of the invisible God, means the Father has an image not presently seen but one day we will when we are in Heaven.
Jesus said that in that day when we are in heaven, we will not need Jesus to ask the father for us but we can go directly to the Father in seeing Him to ask Him directly in Jesus's name.
John 16:23 And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you. 24 Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full. 25 These things have I spoken unto you in proverbs: but the time cometh, when I shall no more speak unto you in proverbs, but I shall shew you plainly of the Father. 26 At that day ye shall ask in my name: and I say not unto you, that I will pray the Father for you: 27 For the Father himself loveth you, because ye have loved me, and have believed that I came out from God. 28 I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.
