To be able to minister in the flow of the Holy Spirit rather that the flesh, a consecration to the Lord is vital. If you are not faithful to the Lord, you will struggle, not only that, we are wise to learn from Moses when he struck the rock the second time and lost entry to the promised land: The more anointed we are, the more responsibility we carry and the deeper the consequences.
Galatians 3:3 Are you so foolish? Having begun in the Spirit, are you now being made perfect by the flesh?
Don’t try but trust in the Lord with all your heart.
