If you have tattoos or earrings do not show that you are a Christian.
For the rest, brothers, rejoice in the Lord. It is not bothersome for me to write the same things to you, and for you it is safe.
Philippians 3: 1
But how many things were for me gain, I have esteemed them as a loss for the love of Christ.
And certainly, I still esteem all things as a loss for the excellence of the knowledge of Jesus Christ, my Lord, for whose sake I have lost everything, and I consider it as rubbish, to win Christ,
and be found in him, not having my own righteousness, which is by the law, but that which is by the faith of Christ, the righteousness that is of God by faith;
in order to know him, and the power of his resurrection, and the sharing of his sufferings, becoming similar to him in his death,
Philippians 3: 7-10
Here we see Paul's statement, today many of us make this statement like many others thinking that as a magical word repeating this or "With Christ I am crucified together."
We understand proclaiming the word of God through FAITH !, but again Faith comes by hearing by the word of God.
We have ALL the right to make use of the word of GOD for "FAITH".
Here Paul reached a stature where he does not strive to leave or estimate by garbage what he was for profit. His stature and his high faith makes him naturally think that for trash and want to win Christ.
So practical is this, We grow through the word and it becomes a reality in our lives, we begin to speak and live the word, we do not strive to let go of our sinful tendencies, and we begin to proclaim this word truly by FAITH, that faith that only comes from God through his word, so without straining we begin to live that resurrected life so desired.
We are still ordinary people, we dress like others, maybe we have tattoos or other things, but even so the life of Christ is manifested, we have the ability "In CHRIST" to live a resurrected life, the same life of Christ reproduced wherever we are.
"If you have tattoos or earrings do not show that you are a Christian." (It's just the title, the life of Christ in us has nothing to do with it).
That's how I think, I believe his word!
