How does one receive the righteousness required to enter the wedding feast?

In the parable, the man without the wedding garment represents those who lack the righteousness that only Jesus provides. According to biblical teaching, true faith involves believing in Christ's completed work and receiving His righteousness by grace. Romans 10 articulates this process, illustrating that faith comes through hearing and believing in Jesus, thus making Him the end of the law for righteousness. It is essential for anyone desiring to enter the wedding feast to be clothed in the righteousness of Christ, distinguishing between mere outward compliance and genuine faith that transforms the heart.
