We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe and therefore speak. 2 Corinthians 4:13
What you are speaking is what you believe. If you speak positive things, you believe and expect positive things. If you speak negative things, than obviously you believe negative things and expect a negative outcome. Perhaps it is time to have a mental check up?
Luke 6:45 tells us that “…out of the abundance (overflow) of the heart his mouth speaks”. By studying the parable of the sower in Matthew 13 we know that the heart of man is the soil where seed (good or bad) is sown. The seeds sown are words. Just as good soil is necessary to produce a good harvest; good seed is also important. Your good soil (heart) can only produce after whatever seed has been sown.
Let’s look at the full text of Luke 6:45(AMP):
The upright (honorable, intrinsically good) man out of the good treasure [stored] in his heart produces what is upright (honorable and intrinsically good), and the evil man out of the evil storehouse brings forth that which is depraved (wicked and intrinsically evil); for out of the abundance (overflow) of the heart his mouth speaks.
What seed are you sowing? What kind of seed are you allowing others to sow?
Keep and guard your heart with all vigilance and above all that you guard, for out of it flow the springs of life. Proverbs 4:23 (AMP)
For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]. Philippians 4:8(AMP)
Once you have received good seed, be sure to water it by meditating on the Word of God. Feed the seed! In time you will see the benefits of a good and bountiful harvest in your heart and in your life.
