Existence is not life. This verse is speaking of EternalLife and AbundantLife that come only to a person who has received Christ Jesus. Those who don`t receive Christ never experience EternalLife or AbundantLife.
By faith in Christ Jesus we receive the gift of EternalLife, the SpiritOfChrist who is the HolySpirit.
Jesus is the object of Faith.
The HolySpirit is the object of fact.
We receive Him (Jesus) who can be seen, by faith so that we can receive Him (HolySpirit) who cannot be seen by gift.
