Humans, we are limited in our thinking and our belief, so beyond just thinking positively, we need to declare positive confession to our life.
Although we are limited, but that does not mean that we must not have positive thinking. God created us that way. If it is only God who is not limited, he has unlimited options and plans for us.
We must count on God in our abilities and know that we are limited in our thoughts must involve God also and our thoughts must align with the will of God, if not, it might not take effect.
God created us and put limits for some certain reasons. The world is not just a place, but many people understand that some people are so many deceived and being afraid by the concept of death. This just makes our minds to be afraid.
None of us is just dying and going. We all have a specific time, which only God knows because of his unlimited. We should cast our cares to God and constantly believe in him. We should put our belief in God always.
The Bible says, we believe that our sufficiency is of God, so we must all our belief must be on God. This is why we are limited. I cannot do this on my own. We must understand that we must put all our trust in God.
