“For to me to live is Christ, and to die is gain” Philippians 1:21.
Only a person with deep and unshakable faith can say that. We may affirm to the statement in our minds, but we have to be of strong faith to say that. Paul saw tremendous things that Christ did around him, in him and through him and therefore could say such a radical statement. He saw that his religious zeal prior to coming to Christ led to nowhere, except pain for others. He saw how sinful he was and his desire to be with Christ was natural. Jesus has to become more real than people around us in order for us to say that. But that is possible!
