Why is the law not of faith?

In Galatians 3, Paul makes it clear that the law operates on a system of works, saying, 'the man that doeth them shall live in them,' which is a stark contrast to the principle of faith. Faith acknowledges our inability to obey the law perfectly and instead relies on Christ’s perfect obedience. The law exposes our sinfulness and sets a standard that we cannot meet, leading to a curse. In contrast, faith submits to God’s provision in Christ, who redeemed us from that curse by becoming a curse for us. Therefore, the law's requirement of obedience stands opposed to the gracious gift of faith that relies solely on Christ's merit.
