Romans 5:3-5…3 And not only this, but we also exult in our tribulations, knowing that tribulation brings about perseverance; 4 and perseverance, proven character; and proven character, hope; 3 And not only this, but we also exult in our tribulations,
Vv.1-2 include all three parts of a Disciples walk with Jesus:  salvation by faith and peace with God,  by faith in the grace we stand as disciples growing in His image and  the hope of glory–heaven with Jesus for eternity.
Because of these steps, the Disciple can exalt in trouble. Dealing with troubles trusting Jesus produces perseverance and the character to trust Jesus for all future events good or bad in the Disciples life in step 2. As you continue to repeat the perseverance-character cycle living a Jesus-centered life your hope or certainty of eternal life with Jesus grows step 3.
So in reality troubles increases our hope for the future. The Disciples body is the temple of the Holy Spirit and the Spirit guarantees our resurrection bodies. A When we purchase a house we provide a down payment to guarantee the transaction will be finalized. The Holy Spirit is a much better than a mere money downpayment.
When the first Disciples saw the reality of the resurrection, ascension of Jesus and received the Holy Spirit they no longer feared what man could do them. They became fearless in sharing the truth of the gospel. They lost their fear of circumstances and earthly death.
The Jesus-centered Disciple can exult in tribulations and serve Jesus and others fearlessly!
