How do we know that God will save His church?

The assurance of God's salvation for His church comes from His unchanging promise and the power behind it. Jesus affirms this in John 6:37, stating, 'All that the Father gives me will come to me,' highlighting the certainty of His elect coming to Him. Additionally, the Great Commission (Matthew 28:19-20) underscores His commitment to building His church until the end of the age. The Holy Spirit actively works within the hearts of God's people, drawing them to repentance and faith, fulfilling His promises and demonstrating His faithfulness.
