How do we know our salvation is complete in Christ?

The assurance of our complete salvation is found in Colossians 2:10, which states, 'And ye are complete in him, which is the head of all principality and power.' This completion comes from Christ’s perfect obedience and sacrificial work on the cross. He fulfilled the law entirely, and through His righteousness, we are justified and sanctified. Additionally, His victory over sin and death grants us assurance that nothing is lacking in what He has done for us. This means that all that we need for our spiritual life is sourced in Christ, affirming that our salvation is finished and wholly sufficient.
