How do we know that God protects His saints?

The assurance of God's protection over His saints is prominently highlighted in Isaiah 54:17, which proclaims, 'No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.' This verse serves as a declaration of God's unyielding commitment to His people. He promises that despite the trials and adversities they face, any scheme or attack from the enemy will ultimately fail. The context of this promise rests on the covenant relationship believers have with God, who is depicted as their Husband and Redeemer.

The basis for such protection goes beyond mere words; it is established on the covenant of grace sealed by the work of Christ. Isaiah 54 essentially elaborates on the victory secured through Christ's sacrifice and resurrection, which not only brings forgiveness but also empowers and defends His people against all forms of spiritual and temporal danger. Thus, the certainty of God's protection reaffirms the sovereign grace doctrine that assures believers of their security and standing in Christ.
