Your election is in Christ unto salvation from eternal judgment. Christ is our deliverance from condemnation. Election is God the Father's choice to save sinners in Christ (Ephesians 1:4-6). Reprobation is the opposite of election. It is the choice of those who reject God's salvation in Christ (John 3:18).
Your election is in Christ by God's grace. He saves us from the condemnation of our sin. God's grace is his goodness, leading us to repentance (Romans 2:4). God commands all people everywhere to repent (Acts 17:30). Those who are lost reject God's grace and goodness (Hebrews 10:29).
Your election is in Christ confirmed through faith (2 Peter 1:1,10). Election gives mercy to sinners through Christ crucified (Romans 5:8). Christ risen from the dead brings justification to sinners by faith alone (Romans 4:5; 10:9). Faith in Christ makes your calling and election sure.
Your election in Christ is confirmed through the gospel. That is to say, your election is in Christ alone (1 Peter 1:1-2). Those who reject the gospel of Christ have no one to blame but themselves. Christ is God's Elect One, and you are elect in Christ (Isaiah 42:1; Ephesians 1:3-4).
Your election is in Christ to the praise of God's glory. God saves us by faith in Christ to the praise of His glorious grace (Ephesians 1:6). To the contrary, God allows those who are lost to reject Christ unto their own just condemnation (John 3:19, 36).
