As Christians, we can have an enduring hope in the promises of God. We have seen him make good on his word. We have seen his great and glorious love for us. We have seen his sovereignty and power. And because of the character of our Holy God, we can have hope through all kinds of trials, desires, and unknown futures. Just as God gave Isaac to Abraham and Sarah when they were in their old age, God will be faithful to all he has promised.
"Let us hold fast the confession of our hope without wavering, for he who promised is faithful." Hebrews 10:23
