At the end of Jesus’ earthly life and ministry, he met with his disciples in the Upper Room. As he compassionately comforted his disciples he said, “But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me. And you also will bear witness, because you have been with Me from the beginning.”
To bear witness is to show that something is true. Or, in a different sense, to speak of the truth that one has seen or experienced. God within us allows us to bear witness because His indwelling Spirit is the Spirit of truth and is constantly manifesting “truths” deep in our bones. There is truth in us - let’s allow it to leak.
