We know that the elect will be saved because Jesus declared that none given to Him by the Father will be lost.
The assurance of the salvation of the elect is found in John 6:39, where Jesus states, 'And this is the Father's will which hath sent me, that of all which He hath given me, I should lose nothing, but should raise it up again at the last day.' This verse signifies that every individual chosen by God will be preserved and brought to eternal life. This guarantee stems from the nature of Christ's mission and the Father's will, ensuring that every soul given to the Son will ultimately be raised on the last day. In the context of sovereign grace, this reflects God's covenant faithfulness and the truth that salvation is entirely of the Lord, not contingent upon human effort or merit. Thus, the elect can rest in the promise that they will be eternally secure in Christ.
