How do we know God's elect are secure in Christ?

John 10:27-29 states that Christ knows His sheep and gives them eternal life, ensuring they shall never perish. This security is grounded in the sovereign will of God; the Father has given these believers to Christ, and no one can take them out of the Father’s hand. This doctrine of perseverance assures us that the salvation achieved by Christ is complete and unassailable by earthly or spiritual forces. Thus, those whom God chooses and saves through Christ will remain secure in His grace.
