How do we know we have security in Christ?

The believer's security in Christ is anchored in God's immutable promises, as articulated in Hebrews 6:17-20. God has confirmed His promises with an oath, ensuring that His word cannot fail. This promise acts as the anchor for our soul, providing both hope and steadfastness. For those who have fled to Christ for refuge, the assurance is that they will not perish, as Christ's righteousness is credited to them. Therefore, believers find their security in the character and faithfulness of God, who has committed to saving and keeping His people eternally.
