Who constructed that barrier that's holding you back? There's a good chance you face a barrier that is not constructed by God. Yes, God will block us at times, but more often we face barriers that are not of God at all.
Barriers of fear, shame, blame, and deception are more often the cause of us getting spiritually stalled out. There is one barrier breaker and he left behind a document that crushes half truths and lies. We need to tear down everything "raised up against the knowledge of God". Taking thoughts captive that have frozen us in our tracks will crush barriers and allow us to walk forward in Christ's confidence.
II Corinthians 10:4-5
