There is no 'other' power than God-within You. Practice Oneness.
The "ME" of you is God. Keeping that in your heart read on
Deuteronomy 31:8 - And the LORD, he [it is] that doth go before thee; he will be with thee, he will not fail thee, neither forsake thee: fear not, neither be dismayed.
Deuteronomy 31:6 - Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he [it is] that doth go with thee; he will not fail thee, nor forsake thee.
