What does it mean to have 'been with Jesus'?

Having 'been with Jesus' signifies a profound transformation that occurs when one enters into a saving relationship with Him. It is characterized by a genuine understanding and acceptance of His teachings, resulting in a life that reflects His righteousness. As seen in Acts 4:13, the council recognized Peter and John as uneducated men who spoke with boldness, attributing this to their time spent with Jesus. This relationship brings about the new birth, imputed righteousness, and a heart aligned with God's will, evidencing that they are truly His followers.
