What does the Bible say about God's patience in calling His servants?

In Exodus 4, we witness God's unwavering patience with Moses as he repeatedly expresses doubts and objections about the task at hand. Initially, Moses questions his own worthiness ('Who am I?'), and God reassures him, saying, 'I will be with you.' Despite Moses' subsequent objections, God's response showcases His mercy and commitment to equip those He calls. This narrative serves as a testament to God's enduring patience with His people, offering encouragement that He empowers those He chooses, regardless of their flaws or uncertainties.
