When considering eternal life, many think of it as a future promise, but it is also a present reality for those born of God. Eternal life begins at the moment of salvation and flows from God’s covenant of grace. Perseverance is the natural outworking of this new life in Christ. We are eternally secure if we are born of God. Yet this assurance should not breed complacency. Instead, it compels us to resist sin, for the Spirit within us continuously transforms us to reflect Christ (1 John 3:9).
Perseverance relies not on our strength but wholly on God’s power. Misunderstanding this leads to striving for assurance in ourselves—a fruitless effort given our inherent depravity. It is Christ's atonement and the abiding presence of the Spirit, not to anything in our imperfect commitment. This doctrine reminds us that justification and sanctification are God's work from beginning to end and that it is His operative work that keeps us from falling, thus assuring perseverance (Romans 8:30).
Perseverance does entail faith, but not as an act of mere human willpower; it requires grace-enabled trust in Christ alone. It involves daily repentance and leaning on the Spirit to convict us of sin and point us toward growth in holiness. This doctrine brings great confidence and rejoicing for being set free from the fear of possibly falling away while it beckons one to rest in the finished work of Christ. It is the hope that reminds the believer that his salvation is not anchored in human frailty but in God's sovereign love. Christians can confidently thank God for the preservation He provides, knowing that nothing can separate us from His eternal hold.
