Hearme, What you say out of your mouth and believe in your heart is what you are going to get.
You are NOT immune to the blessings of God but you are opening yourself up to the enemy when you say such things because your confession is going against the Word of God.
Line up what you say out of your mouth and what you believe in your heart with the precious promises of God and then and only then, will your life change.
This is what the Bible states about you and is what you need to be confessing out of your mouth and believing in your heart.
Blessed be the Lord, who daily loads us with benefits, even the God of our salvation. Selah. Psalm 68:19
