You can know you have eternal life by believing in the name of the Son of God, as assured in Scripture.
The assurance of eternal life is straightforwardly presented in 1 John 5:13, where it states that those who believe in the name of the Son of God have eternal life. This belief is characterized by a heartfelt recognition of one's sinfulness and a reliance on Christ's redemptive work. It’s essential to focus not on feelings of doubt or weakness but on the object of that faith—Jesus Christ. When you believe in Christ, it reflects the internal testimony that God has placed within you, demonstrating that you are one of His elect. This verse serves to reassure believers that their confidence should stem from their faith in Christ, not from their actions or perceived shortcomings.
