Luke 21:15 (KJV) states, "For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist." This verse is part of a larger passage in which Jesus is giving his disciples warnings about the signs of the end times and the persecution they will face as his followers. In this particular verse, Jesus is assuring his disciples that they will be given the words and wisdom to speak against their adversaries.

The context of this verse is important to understand its full meaning. In the preceding verses, Jesus tells his disciples that they will face persecution and hardship for their beliefs. He warns them that they will be brought before authorities and faced with opposition, but at the same time, he encourages them not to worry because the Holy Spirit will give them the words to speak. This verse, then, is a reassurance to the disciples that they will be given divine guidance and help to navigate the challenges they will face.

The theme of this verse revolves around the idea of divine assistance in times of trouble. The disciples are told that they will be given the gift of wisdom and the words to speak that will confound their adversaries. This theme of divine guidance and support in the face of opposition is a recurring one in the Bible and serves as a source of strength and encouragement for believers facing difficult circumstances.

The symbolism in this verse is significant as well. The "mouth" given to the disciples represents the ability to speak the truth and defend their faith. The "wisdom" symbolizes the divine insight and understanding that will guide their words and actions. The fact that their adversaries "shall not be able to gainsay nor resist" signifies the power and authority of the message they will speak, which will be impossible to refute or overcome.

This verse has broader implications for Christian believers today. It serves as a reminder that, just as the disciples were promised divine assistance in their time of need, so too can modern-day believers trust in the guidance and support of God when facing challenges and persecution. It encourages believers to rely on the Holy Spirit for wisdom and strength, knowing that they will be empowered to speak the truth and stand firm in their faith.

In conclusion, Luke 21:15 (KJV) is a powerful and reassuring verse that speaks to the theme of divine assistance and support in the face of opposition. It serves as a source of encouragement for believers facing persecution and challenges, reminding them that they will be given the words and wisdom to speak against their adversaries. The symbolism of the "mouth" and "wisdom" given to the disciples signifies the divine guidance and authority that will be bestowed upon them. This verse continues to be a source of strength and hope for believers today, pointing to the abiding presence and support of God in times of trouble.
