Assurance of election comes through faith in Christ and the transformative work of the Holy Spirit in our lives.
Believers can be confident of their election by recognizing the work of the Holy Spirit in their hearts, leading them to faith in Christ. In 2 Thessalonians 2:13, Paul notes that those chosen are called through the gospel and sanctified by the Spirit, implying that true faith and repentance are evidence of being among the elect. The internal witness of the Spirit, coupled with an active faith and a life transformed by God's grace, provides assurance that one's calling and election are real. Additionally, the promises of God assure that He will keep those He has chosen.
