Forgiveness is a fundamental characteristic of a disciple of Jesus. It is paramount to our faith in terms of the cross, and the hope in a King who left Heaven to die for His creation upon it. Without forgiveness, we would be a lost creation, destined to live a finite, empty life. But with His forgiveness; infinite, eternal possibilities are now available to man.
For Christianity, one of the foundational beliefs is that the Bible is the inspired word of God.
Given that the Bible fulfills the first requirement to be considered inspired (that it claims to be the inspired word of God), Christians are tasked with proving its claims to be true. There are many ways to go about doing so, since the Bible possesses many characteristics that help to prove its claim of inspiration.
Matthew 19:13-15 (ESV)
Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people, but Jesus said, “Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.” And he laid his hands on them and went away.
