In Buddhism, wrongdoing is considered ignorance of reality. There is only a life of suffering due to selfish desires and possessive loves. So, the whole effort of Buddhism is to eliminate suffering by following the Eightfold Path. To achieve Nirvana or liberation from suffering means to abolish the illusion of self. "Life is a transition without substance (illusory) and filled with suffering. All life is, therefore, meaningless and without purpose. ... Redemption is the complete departure from endless cycle of birth, death rebirth and release from self into nirvana and silence. Nirvana is the impersonal ultimate reality; whether or not this state is conscious is not defined." (Website: Dr. Chik Kaw Tan, Can One be a Christian and Buddhist at the same time?)
Christian metaphysics is quite different. The Buddhist D. T. Suyzyky states, "Whenever I see a crucified figure of Christ, I cannot help thinking of the gap that lies deep between Christianity and Buddhism." Sin and suffering is the work of man from the beginning. Humanity fell into Sin and suffering through Adam and Eve but God in his mercy sent his Son restore our relationship with God. The Crucified Christ is a constant reminder to Christians of the love of God for mankind. Unlike Buddhism, wrongdoing can be forgiven and suffering in Christ has meaning for eternal life. Our destiny is not Nirvana but Heaven, a living union with God in the happiness of heaven.
Buddhism does not know the meaning of suffering because it does not know God. It struggles internally to get rid of ignorance and ultimately to get rid of self and reach Nirvana. "Jesus himself declared that He is the way, the truth and the life, and on one can come to the Father except through Him." If that is true, other ways cannot be true." Buddhism cannot be the true way into God's kingdom.
