To overcome our doubts and and anxiety we must live our life solely depending on God for answers to all of our quest.
Fear is what put us into slavery, when we live a life of doubt, we dwell in fear, the fear that we might be swallowed by our challenges.
As believer, we must live a lifestyle of faith as faith makes us overcome anxieties.
A dedicated commitment to the word of God will eradicate doubts and anxieties.Because our life is a product of what we read and the people we associates with. So daily commitment to the word of God will make us have the minds of Christ and in the mind of Christ, there is no doubts.
When we portrays this, we have peace and passed all understanding.
