The Lord be with you today!
Just a different path to take on the first question that I didn't see anyone else bring up, besides the route of where others have went in their replies being the encouragement route, but I am also reminded of how it is in a court situation, or a trial. Yes, we our witness encourages us and gives us hope but when we give witness to the unbelievers around us we are in fact also making the case against them as well. Think about it, when the unbeliever stands before the judge, God almighty what evidence will the almighty have against them? Our testimony as to how we witnessed, behaved and were mistreated by these persons. Rarely in a court will a person be convicted on the witness of one person. Not only will the almighty have the intentions of the heart, but also our testimony.
Jesus is the first witness....he is the faithful witness because He did not compromise his message or his testimony and remained faithful which leads into our last question of our inability to be faithful witnesses even in a culture where we are not "severely" punished for our message. But I do believe the shift in this country is moving in that direction. We are already ridiculed for our testimony and our choices...and I can only forecast it as getting worse. Jesus' example to us was the perfect one, and our Lord being the only perfect in the flesh should encourage us as even our petty attempts to be witnesses of our Lord's plan and will are just that only petty. Remember that folks...when you mess up
