How do we know that God never fails?

The assurance that God never fails can be seen throughout the biblical narrative. In Joshua 15-17, God promised the Israelites victory and guidance in conquering the land of Canaan. The struggles they faced were a result of their lack of faith, not a deficiency in God's ability or willingness to fulfill His promises. Every failure or setback in Scripture is ultimately tied back to human unbelief rather than God's unfaithfulness. As believers, we can rest in the truth that God always accomplishes what He sets out to do, despite our shortcomings and weaknesses.
