How do we know God's elect will be saved?

We can know that God’s elect will ultimately be saved because salvation is grounded in the finished work of Christ, who saves to the uttermost those who come to God by Him. This is affirmed in Hebrews 7:25, which states that He is able to save completely those who come to God through Him. The assurance of salvation for the elect is not based on human effort, but rather on God’s unchanging purpose and promise. The faith of the elect is a gift from God, not something they achieve by their own merits.
