How can we know we have eternal life?

According to 1 John 5:20, knowing the Son of God and accepting Him gives us understanding that leads to eternal life. This assurance is internalized through the Holy Spirit, who confirms our faith and bears witness in our hearts. Eternal life is not merely future hope but a current reality for believers, marked by the transformation of life and the presence of God’s love within us. Moreover, Romans 6:23 highlights that the 'gift of God is eternal life through Jesus Christ our Lord,' affirming that eternal life is a divine gift received by grace alone, which assures believers of their standing in Christ.
