How do we know that salvation is not based on the law?

In Galatians 3, Paul asserts that those who rely on the law are under a curse because no one can keep it perfectly. He states that Christ has redeemed us from this curse by becoming a curse for us, thus fulfilling the law's demands on behalf of those who believe. This truth confirms that our salvation is grounded not on our ability to adhere to the law but solely on the grace of God extended to us in Christ. Thus, salvation is seen as a gift, highlighting our complete reliance on Christ's finished work for redemption rather than our works.
