How does God's grace relate to regeneration?

Regeneration is intrinsically linked to God's grace; it is solely by His grace that we are given new life. In Titus 3:5, Paul writes that we are saved not by works of righteousness that we have done, but according to His mercy, through the washing of regeneration. This indicates that regeneration is a gracious gift from God, initiated by His will and not our own. The requirement of being born again, as stated in John 3:7, highlights that regeneration is essential for entering the kingdom of God, affirming that it is through grace that we find restoration and renewal in Christ.
