In John's Gospel we find key teachings on work education:

1. continuous education and growth: Jesus spends time teaching and preparing his disciples for the work that awaits them. This teaches us the importance of continuous education and growth in our work, seeking to learn and develop our skills to be more effective and relevant in our work.

2. Faith and trust in God: Jesus emphasizes the need to trust in God and seek His direction in all that we do. This teaches us to depend on God's guidance and strength in our work, knowing that He is present and that we can trust in His provision.

3. The importance of service and humility: Jesus shows us that true leadership at work is based on service and humility. He himself humbles himself by washing the feet of his disciples and calls his followers to do the same, serving others with love and generosity.

4. Perseverance in the midst of adversity: The Gospel of John shows us how Jesus faces different adversities, but does not give up or abandon his mission. This teaches us the importance of perseverance and resilience in our work, even when we face difficulties and setbacks.
