Christian hope is grounded in the sure and unchanging nature of God, who cannot lie. This hope is not mere wishful thinking but a confident assurance based on God's immutable purpose and promises. If God declares that certain events will come to pass, it is reasonable and safe for us to hope confidently in them. His unchanging character ensures that His plans and actions remain steadfast, producing outcomes that always end in good. The immutability of His counsel, an unbreakable and fixed purpose, provides spiritual support, helping us to lay hold of the hope set before us. Without this fixed truth, there would be no foundation for belief or confidence in His promise of salvation. God's guarantee, as recorded in Isaiah, affirms that what He has spoken and purposed, He will bring to pass. This unchanging nature of God is a comforting assurance, allowing us to trust in His counsel and plans that stand forever.

In the hope of eternal life, which God, who cannot lie, promised before time began, we find the assurance of our ultimate goal. God's promise stands firm, as He never deceives or misleads; there is no trickery or betrayal in His plan. His truth is unwavering, a foundation that has always been part of His purpose for us. This hope, rooted in His unchanging nature, guides the work of His ministers to lead and support the faithful toward the Kingdom of God, ensuring that the path, though filled with trials, remains certain for those who endure in faith.

Abraham's faith in God's unchangeable character shines through in his response to the command to sacrifice Isaac. He remembered God's clear promise that his descendants would come through Isaac, as stated in Genesis 21:12. Abraham understood that God's word is sure, for His God does not lie. He does not speak foolishly or raise hopes only to dash them. Knowing this, Abraham reasoned that Isaac must live to fulfill the divine promise of descendants as numerous as the stars of heaven and the dust of the earth. This assurance led him to conclude that even if he had to slay Isaac, God would resurrect him to keep His word. Abraham's confidence in God's faithfulness allowed him to tell his servants that both he and Isaac would return from the mountain, certain that God would not renege on His promises. His trust in a faithful, truth-speaking God underpinned his hopeful obedience, demonstrating that God always upholds His commitments.
