It is only something that is dead, that can be reborn. If you have not died to the flesh, how then can you be reborn (be born again). That is why Jesus says in John 12:24-26 Verily, verily, I say unto you, Except a corn of wheat falls into the ground and die, it abides alone: but if it die, it brings forth much fruit.
If the unbelievers around you cannot boldly say that you are truly a Christian, then your Christianity is still at the level of religion and not following in the footsteps of Jesus Christ. What it means is that you are just converted and not yet convicted by the Holy Spirit.
How you approach any circumstance in life will determine how you will come out of it, whether you win or fail; and positivity attitude towards life will always make you a winner. Your attitude is more important than the situation.
Christianity is not a religion, it is God's way of life, it is living God's Will, it is behaving like Jesus Christ. It is being led by the Holy Spirit who constantly reminds you of the Will of God and guides you into all Truth. Christianity is the Culture of heaven.
Many who allowed anxiety to creep into their lives, only have stories of regrets and scars of failure to show for it. It does not add anything positive to your life, but it takes away everything from you.
Do not wait till tomorrow to embrace the light for the world is full of darkness and habitations of cruelty. There is no peace in the world because the world is not capable of actual peace which only Jesus Christ, the Prince of Peace can give; the Peace that passes all understanding, not as the world gives.
