The bible speaks of God breathing on the dust of the earth to form Adam (genesis 2; 7.) breathe is the symbol of life, God's own life secretly hidden inside every unique individual. When God creates human beings no matter what gender, Christians believe that they are totally unique; we alone can appreciate the wonder of creation, can love, can choose, can seek to grasp the meaning of life, and can come to know the God that made us. By taking the responsibility to look after our life as we know it, we are appreciating the great gift that God has given us and thanking him for the creations that he has made.
Christians should be grateful for life and appreciate the wonder of the gift of life and of God's love, which means living life to the full and following in Jesus footsteps and abiding by the Ten Commandments. Christians believe that god creates life and only god should be able to take life away. Precisely because life is such an amazing gift it is an appalling evil when it is deliberately destroyed or irresponsibly endangered. Through Jesus we saw hope special life was and to what extreme god would put Jesus through to save the lives of others. In Jesus' crucifixion we see how determined Jesus was to save the lives of other Christians whether or not he sacrificed his own life on the journey.
The second Vatican council spoke of our inescapable duty to make ourselves the neighbour of every individual and pointed to the most serious crimes by which the lives of others are disregarded or destroyed. If Christians believe the human life is sacred then we should have a responsibility in our lives to make the right moral choices, receiving a sacrament can give us the strength and courage that we need to do this. We could make the right decision by making ourselves the neighbour of absolutely every person, and of actively helping him or her when he or she crosses our path, Jesus done this many times during his life. He healed many people during his time on earth for example; blind Bartimaeus, Jarius' daughter and the woman with the haemorrhage.
God made human life sacred, therefore we should have the responsibility in our lives to be grateful for the extraordinary creations that he has made and respect our lives, we can do this by treating them dignity and not neglecting our duties as a Christian. To show how thankful you are you would live your life to the full and not risk your life or deliberately destroy it. Christians who do this will be serving God, which can be done in many ways for example looking after others in their community or the community of the entire world. Life is a wonderful thing which should not be purposely destroyed for any reason it is a sacred gift given to us by God and every unique life that is taken away from the world takes away a unique cleverly disguised creation of God.
