For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. Mark 11:23
Most Christians who are defeated in their finances are defeated because they believe and confess the wrong things. They have spoken the words of the enemy, and those words hold them in bondage. Jesus said in Matthew 17:20, ...for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
And in Mark 11:23, For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
In these passages of Scripture, Jesus tells us that what we believe and speak affects the natural world, including our finances. God has given us His Word so that we can understand these spiritual laws that govern the universe. There are spiritual laws just as there are natural laws, such as gravity and the law of lift. When you work with these laws, they work for you. When you work against God's spiritual laws, they work against you.
When you speak negatively about your financial situation, you can have what you say and believe.
Here is a very important spiritual law: You can have what you say.
With your words you can choose life or death, poverty or riches, sickness or health. You may tithe (give 10 percent to the church), work hard, and pray for prosperity every day, but if your words are negative and contrary to God's Word, you could stay mired in debt, struggling to make ends meet.
Words are powerful, but God's Word is full of creative power. When you agree with what God has said about you and speak His Word, your circumstances will begin to change and line up with His will for your life.
