What assurance do believers have regarding their salvation?

The assurance of salvation is a foundational aspect of Reformed theology, reinforced by Jude 24-25, which states that God is able to keep believers from falling and will present them faultless before His glory. This assurance stems not from personal righteousness, but from the perfect work of Christ and His promise to preserve His people. In the face of struggles and the temptation to stray, believers can take comfort in knowing that their salvation does not depend on their ability but solely on God's grace and power. Through faith in Christ, they can rest in the reality that they are secure and will not be lost. This hope brings joy and strengthens the believer’s resolve to live in a manner worthy of that calling.
