How do we know that salvation is guaranteed?

The assurance of salvation for believers rests on the immutability of God's counsel as highlighted in Hebrews 6:17-18. God’s promise to those who flee for refuge in Christ is corroborated by an oath, emphasizing that His commitment is unwavering and true. This theological foundation allows believers to confidently affirm their salvation, as it is not contingent on their actions or faithfulness but fully dependent on God's grace and His faithfulness to His word. The understanding that He cannot lie grants an unshakeable foundation for assurance that we are eternally secure in Him.
