How do we know God's promises regarding salvation are true?

The veracity of God's promises concerning salvation is supported by Scripture, particularly in John 6:37, where Jesus states that anyone who comes to Him will never be cast out. This assurance is grounded in the nature of God Himself—rich in mercy and faithful to His word. Furthermore, the resurrection of Christ is a pivotal event that assures us of our salvation and the promise of eternal life for those who believe. Additionally, the consistent biblical narrative underscores that salvation is by grace through faith alone, reassuring believers that their salvation is secure in Christ and not dependent on their own works.
