In the Christian perspective, human beings are valuable because they are in God's image this genuinely means human life possesses dignity and value of life because it is created by God in his own image for the distinctive destiny of sharing in God's own life.
Another representation of this is that to advise euthanasia for an individual is to judge that the current life of that individual is not worthwhile. This judgement is also fitting with recognising the worth and dignity of that person to be killed. The Bible also explains that no one has the right to value anyone, even themselves as worthless.
The process of dying is spiritually important, and should not be disrupted as many Christians believe that the life just before death is deeply a spiritual time. They also consider that it is wrong to temper with the process of dying, as this would interrupt the process of the spirit moving towards God.
Christians accept that all human lives are equally valuable, They don't think that human dignity and value are measured by mobility, intelligence, or any achievements in life. Christians bring up facts that patients in an endless vegetative state, although seriously ill, remain living human beings living their daily lives, some independently, some cared for by family or carers. And so their values remain the same as anyone else's. So it would be wrong to treat their lives as worthless and to conclude that they 'would be better off dead'.
Specific features of Christianity suggest that there are some obligations that go against the general view that euthanasia is a bad thing. According to Christians, Christianity requires us to respect every human being, if we respect that person we should also respect that if a person decides that they are about to or thinking of ending of their life.
In conclusion Christians believe that life and death can only be given and taken by God, it is no humans duty to end another's life as it wasn't their duty to being their life in the first place. A lot of Christians who are strong about their beliefs and believe strongly that life shall be ended normally would, they would never tempt a human being to end their life as it is so valuable and dignified and it would be not only letting yourself down but letting God down.
