Election is the gracious purpose of God, according to which He regenerates, justifies, sanctifies, and glorifies sinners. It is the glorious display of God’s sovereign goodness, and is infinitely wise, holy, and unchangeable. It excludes boasting and promotes humility.
All true believers endure to the end. Those whom God has redeemed in Christ and sanctified by His Spirit will never fall away from the state of grace, but shall persevere to the end. Believers may fall into sin through neglect and temptation, whereby they grieve the Spirit, impair their graces and comforts, and bring reproach on the cause of Christ and temporal judgments on themselves; yet they shall be kept by the power of God through faith unto salvation.
