Analysis famous African American boxer # 1

This poster seem to be a guy who is in the military and that is a boxer is trying their best to go after whoever that they are going to attack with.  They want to do the best they can so the can win and that they say their on "God side". Also it seem like whoever they going to get into it or what not they are going to do the best they can to win and with God on their side they think they really have that support to win and not to lose to anyone.  This poster think seem to be quotes of context or either half-truth because in the poster it say they they going to do their part and win because they know that God is on their side to help them out and support them all he can.  It's half-truth because it's just showing one side that they going to win but then who are they going after for or that they don't know what if they might lose?  How is he a boxer if he hold like a gun knife thing, it seem to be more like he in the military or about to get ready to go to war.  How it seem to be explicit is that it look like it already have some to do and that they going to take care of it cause they know they have someone on their side trying to support it. How it is implicit is that it seem like they think and know that God really on their side but then if they lose what are they going to do next, and that how can they think that they going to win if they don't know if the people who they going against is going to defeat them?  This seem to catch people attention because of the quote that it has on the poster and mostly a lot of people believe in God and is willing to know that they going to win because God is on their side.  This seem like it was out in the 1950's or 1970's because it seem to look that old and that time cause of the quote that is on their and how it say famous African American boxer.
