How do we know our salvation is fully accomplished?

The assurance of salvation being fully accomplished comes from understanding that salvation is entirely the work of God. As highlighted in Colossians 2, believers are told they are complete in Christ. Salvation is not an ongoing process needing our additions; it is a definitive act of God through Jesus Christ. The Scriptures affirm that our sins were nailed to the cross, and all necessary righteousness is fulfilled in Him (Ephesians 1:7). This assurance is not found in our feelings or personal works but resides in the certainty of what Christ has done on our behalf, providing full assurance of our status before God.
