We know God's promises are fulfilled through faith in His character and the examples seen in scripture, such as those of Hannah and Abraham.
The reassurance of God's promises being fulfilled comes from both His unchanging character and the historical accounts documented in Scripture. As seen in the life of Hannah, her deep struggle with childlessness led her to fervent prayer, and ultimately, her prayer was answered with the birth of Samuel. Similarly, Abraham waited many years for God's promise of a son, Isaac, and despite seeming impossibilities due to age and circumstance, God's faithfulness proved true. Romans 4:20-21 highlights how Abraham was 'fully persuaded that, what he had promised, he was able also to perform.' Thus, the assurance that God’s promises are fulfilled lies in His ability to go beyond human limitations and fulfill His word according to His perfect timing.
