Can a Christian be certain of his salvation?
Arminians claim that Christ died for all people, so Christ died for them too. But they still say that even though Christ died for them, they may lose their salvation and die the second death (in hell). Such a monstrous doctrine must be exposed for what it really is.
Assurance and perseverance in the Christian faith cannot contradict each other. Arminians involve themselves in hopeless contradictions because they are unable to take God's testimony about our salvation as it stands.
All Bible doctrine is one chain, one doctrine resting or else leading to another doctrine, so that God's truth is one complete whole, harmonious and healthy for the soul.
Assurance belongs to the believer who has duly considered the salvation that belongs to him, freely granted to him by the Triune God. His is not a false hope (Romans 5:5): he knows that he is in a state of salvation (Galatians 2:20; 2 Timothy 1:9, etc.), and thus, out of gratitude, will endeavour to walk in all good conscience before God (Romans 12:1ff). His is the assurance of faith based on the blood and righteousness of his Substitute (2 Corinthians 5:21). He also knows that the spiritual transformation in his heart, wrought by the Spirit, indicates that he is born again (1 John 3:9). He has the witness of the Spirit too (Romans 8:16).
Thus the believer, responding to God's love towards him, endeavours to walk diligently in holiness, making his calling and election sure for himself, subjectively (2 Peter 1:5-11). And though his assurance may be shaken and diminished and even taken away, yet he will persevere unto the end (Philippians 1:6). God, by his power, will keep him (1 Peter 1:5) and will continue to work in him faith, repentance, love, joy, hope and other virtues that lead to immortality (John 10:28-29; 2 Timothy 2:19; 1 John 2:19).
Throughout his life the believer is subjected to trails, temptations and tests (James 1:2ff) but these storms will not sweep him off the foundation and rock. God is the same and keeps his covenant, for his name is written in the Book of life from all eternity (Luke 10:20).
Assurance and perseverance belong to the believer for these do not depend on him or on his free will. Rather they rest upon the decree of election (Romans 8:30; 9:11-16), upon the efficacy of Christ's blood and intercession, and upon the union which true saints enjoy with him (1 Corinthians 6:17). Perseverance rests upon God's solemn affirmation (Hebrews 6:17-18), upon the sealing of the Spirit (Ephesians 4), and upon the seed of God in him which cannot die (1 John 3:9). And all this issues from the covenant of Grace (Jeremiah 32:40), which stipulates that saved souls will never turn away.
Believers will be kept, through faith in Jesus Christ, till the end (Luke 22:32, 61-62).
When one considers all this, then assurance is the inevitable outcome. Assurance flowers from the preservation that God promised to work in believers. So if Christ died for me, then my debt is paid once for all, and death cannot touch me.
