Through Him also we have [our] access (entrance, introduction) by faith into this grace (state of God's favor) in which we [firmly and safely] stand. And let us rejoice and exult in our hope of experiencing and enjoying the glory of God.
Moreover [let us also be full of joy now!] let us exult and triumph in our troubles and rejoice in our sufferings, knowing that pressure and affliction and hardship produce patient and unswerving endurance.
And endurance (fortitude) develops maturity of character (approved faith and tried integrity). And character [of this sort] produces [the habit of] joyful and confident hope of eternal salvation.
Such hope never disappoints or deludes or shames us, for God's love has been poured out in our hearts through the Holy Spirit Who has been given to us.
