We can know we have saving faith by examining our lives for evidence of belief in Christ and love for others.
The assurance of saving faith comes from a personal examination of one's heart and actions. In 1 John, it is stated that we know we have passed from death to life because we love our brothers (1 John 3:14). This love is evidence of faith working within us. Paul instructs us in 2 Corinthians 13:5 to examine ourselves, encouraging believers to look for signs of faith, such as a belief in Christ's redemptive work and growth in holiness. Moreover, authentic faith produces a change in character, leading to a life that seeks after God and loves others.
