Walking by faith is not a “private matter” as some would say. My experience is that anyone claiming that exemption is not walking by faith in any possible way. Christians are “overt” not “covert” followers of Christ. As such we wear our faith publicly and proudly knowing we will not be ashamed because “In God we trust”. Our faith is unfailingly founded on our unfailing Creator! “12 For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day. 13 Hold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesus.” 2 Tim 1:12-13 (KJV)
