Revelation gives us a vision of "what was, what is, and what is to come" as it relates to the phases a church and believer can and have experienced. Its a testimony and witness that is set up to show us what we shouldn't do, (e.g...idolatry, lukewarmness) and what we should do to overcome and be a faithful witness. It gives us purpose and strength thru providing us with "THE faithful witness", Jesus Christ, as the example we should live and walk by. He is the perfect and faithful for all eternity. Rev 1:5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,....This encourages us that it is possible to live beyond the grave because of a prince who took it upon himself to die for us and cover us with His blood so that we might be brought under the light of the Father.
If we are afraid to be clear witnesses in a culture where we aren't persecuted (if by that you mean USA). I am not certain if there isn't a country where Christians aren't being persecuted, it may be different degrees of persecution and some much worse than others. But even in the culture of the USA, I see persecution or forms of punishment, not being allowed to carry our witness into the public sector, our workplace, our schools, etc. If we do, we are subject to some form of punishment, not death necessarily, but loss of jobs, expelled from schools, etc. But if you mean a clear witness around friends or associates, then there is fear of rejection, being laughed at, ridiculed, or loss of friends.
Although I have read and studied Revelation a couple of times now. I feel strength abounding in me right now as I read these questions and write these words. I see Jesus, as a King of Glory telling us we can overcome, dont sit on the fence, take a step and I'll be there to see you through any persecution. Amen and Glory be to God for His mercy and grace.
