How do we know that trusting in Christ leads to salvation?

The assurance of salvation through trusting in Christ is grounded in His role as the author and finisher of our faith. Jesus Himself explicitly states in John 14:6 that He is the way, the truth, and the life. This fundamental aspect of faith underscores the reality that salvation is entirely a work of God, initiated and completed by Christ's atoning sacrifice. Moreover, Romans 10:9-10 articulates that with the heart, one believes unto righteousness, and with the mouth, confession is made unto salvation. This confirms the promise that all who genuinely trust in Christ will not be ashamed, highlighting the security of our salvation in Him.
