As Christians, we can fall in sin daily. The first bulls-eye chart would probably represent Jesus. In using terms of research for fun, Jesus represents reliability and validity. Jesus is the perfect instrument that God sent to die for our sins. It's because he is mentioned in the Bible as the Son of God; not only was Jesus a man, he was also God in human flesh. Now that's pretty hard to grasp for some people; nothing is impossible for God, which would not be hard to figure if one truly does believe in God of the Bible. Jesus came to die for our sins and that we may come to have a relationship with the father. This makes Jesus very valid. In terms of reliability, Jesus has a record in the Bible of never having sinned against God; in other words, why would he if he's also God? Jesus has said in the New Testament that he and the Father (God in heaven) are one and the same, which really ticked off a lot of Jewish leaders back in the day. They have called him a nut and because of his influence with the people, they found a way to crucify him and partied hard on that day. I'm sure some Jewish people to this day would still feel the same way after hearing what Christians profess about him. I'm not saying all Jewish people care for religious things, so I'm not coming across as anti-Semitic. What makes Jesus even more of a valid appeal to question is that the Bible says he rose from the dead to validate God's promises of everlasting life and for the disciples to spread the gospel.
The second bulls-eye after the first, is basically having good reliability but really no validity. It's like measuring an apple in grams with a ruler. We would still get the same measurement each time, but a ruler isn't supposed to be used for finding out an object's weight. I'm thinking for an obscene example, sorry, it's a man who is very successful and then goes through a mid-life crisis while making everyone happy.
The third bulls-eye is like born-again Christians. They are made perfect because of making themselves right with God, but they go on sinning again anyways. These type of Christians are valid in that they hit the bulls-eye by trusting in Jesus, but they are not very reliable because they will continue to go on sinning. From my experiences, the worst type of fall-out came with other Christians. They have said and done things to fill me up with discontent and lots of issues against them. Yet, I'm a Christian too and from reading the Bible, I feel that the right thing to do is to forgive them and move on, so that's what I have been learning to do more each day.
The last one is basically for people who are all over the place and with really no goals. I guess it could be for people who visit both sides of being conservative and then liberal. I don't know if those types of people exist. They can just be morally crazy in a sense and so unpredictable and with really nothing to be validated for.
In conclusion, unless you are God, you have or will miss the target of being perfect. I will be getting back to reading the Bible again and examining some verses to the best of my ability, as I really haven't been reading and just listening to sermons.
