We embody what we believe to be true about the God through our works, such as with James 2:18 saying that he would show his faith through his works. In other words, the way to believe in God is by embodying His character traits. For example, by being a doer of good works in obedience to the Law of Moses we are embodying God's goodness, which is why our good works bring glory to Him (Matthew 5:16), and by embodying God's goodness we are also embodying the belief that God is good. Likewise, the way to believe that God is compassionate is by being compassionate (Luke 6:36), the way to believe that God is holy as by being a doer of His instructions for how to be holy as He is holy (1 Peter 1:16), and so forth. The Son the radiance of God's glory and the exact likeness of His character (Hebrews 1:3), which he embodied through his works by setting a sinless example for us to follow of how to walk in obedience to the Law of Moses. So does the God that you believe in have the character traits that the Law of Moses was given to teach us how to embody? If so, then your goal should be to know Him by embodying His character traits in accordance with Christ's example of obedience to the Law of Moses.
