Timothy Paul Jones, co-writer of PROOF, articulates well why perseverance is a gospel issue. If a Christian can forfeit or lose or reject their salvation, then grace by definition is lost. Consequently, the gospel itself is lost.
Jones describes how many today perceive that salvation begins with God’s grace, but is kept by our own effort. He continues saying,
Seen this way, our salvation begins by God’s grace — but then it’s up to us to stay saved. Whether or not we remain in God’s good graces depends on our choices. Perhaps there are certain unpardonable sins that must be avoided or certain levels of growth that must be maintained or even religious rites that must be performed. Jesus starts it, but we finish it. But God, according to the scriptures, doesn’t only start our salvation; he plans it and guarantees it from beginning to end…It’s clear throughout the scriptures that the Father, Son, and Holy Spirit are working together at all times to sustain our salvation to the very end of time.
- The Father plans our salvation to the end, “He who began a good work in you will carry it on to completion until the day of Christ Jesus (Philippians 1:6)
- The Son promises to carry out our salvation to the end: Jesus is both “the pioneer and perfecter” of our faith (Hebrews 12:2). In other words, Jesus doesn’t start our faith as the pioneer, but then leave us to finish the project. Jesus is the one who brings it to completion as “the perfecter” of our faith as well.
- The Spirit guarantees our salvation to the end: God “put his Spirit in our hearts as a deposit, guaranteeing what is to come” (2 Corinthians 1:22).
That’s good news for believers in Jesus Christ because it means you don’t have to keep up the payments on your salvation! If you’ve trusted Jesus, it’s not because you planed that faith in your fleeting and faulty wisdom. It’s because God set his heart on you from eternity past; God made this choice knowing everything about you — past, present, and future! As a result, nothing can change his choice to pour out his grace on you.
Not your sin.
Not our fears.
Not the darkness that gnaws at your heart that no one else knows about.
Nothing in your future.
Nothing in your past.
Nothing in all creation.
Nothing at all can separate you from God’s love.
God proved his love for you once and for all through the cross of Jesus and the empty tomb — and nothing can change his determination to save you by his grace. That’s the promise of forever grace. Forever grace means that God preserves us in his grace and that we persevere by this same grace. Both of these realities are rooted in God’s gracious work. Neither one is a work that originates in us, and both truths are essential. We can glimpse both of these truths at the same time in the same verse in Paul’s letter to the Ephesians: “And do not grieve the Holy Spirit” (that’s a command to persevere) “with whom you were sealed for the day of redemption” (4:30) — that’s an assurance that you will be preserved… God’s planning never writes a check his power can’t cash!
What a comfort to know that if God has saved us in Christ, he will keep us in Christ. He will preserve us, and ensure that we will persevere until the end. As Douglas Wilson once said, Works-righteousness “is a barren mother; she will never have any children, much less gracious children. Grace is fruitful; her children are many, and they all work hard“.
