Everything in creation including man started with a thought.
Nothing will happen until your thought pattern aligns with the thoughts of God.
God is unlimited, with Him, anything is possible. The only thing capable of limiting Him is your mind.
Every limitation starts with fear (of something or the unknown)..Fear is a product of your thoughts.
Two kinds of heart were illustrated;
i. The evil heart - unbelievers can be said to have this. Mark 7:15, 21-23
ii. The negative heart
Psalm 73 is a typical example of a believer with a negative heart.
Instead of bellyaching on what seems to be going well in the life of someone who doesn't serve God like you do..or someone who doesn't believe in God, to the extent that you think God is unfair to you, focus on the capability and faithfulness of your God!
In winning the battle to constantly fill our minds with faith filled thoughts; your word level determines your victory level! Fill your mind with the word of God.
Stay away from scorners- profane people who don't take the word or things of God seriously.
Shut the negative thoughts down.
The seed of your next action is in your current thoughts! I hope those thoughts are faith-filled?
