Proverbs 18:21 says, "death and life are in the power of the tongue, and those who love it will eat its fruits." So, I hope you are being careful about how you speak over your life and are careful of what you entertain regarding what others say to you. I take positive self-talk seriously especially at this point in my life. I've been through enough ups and downs, that I have made a conscious choice to trust what God has to say over my life more than what any man has to say. And I do, not under any circumstances, let nonsense in. How about you? Are you at that place in your life? If not, there is still hope. There is still hope for all of us to get what God has for us. Just remember, it starts with thinking positive, speaking positive, and acting positive. Accept nothing less than that. I'm not talking pie in the sky, I'm talking about what has worked in my life for quite some time.
So yes, speak positive over your life by putting positive words in the atmosphere. And stay in tune with what Isaiah 55:11 says, which is, "my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and shall succeed in the thing for which I sent it." That's right.
