We all have things in our past that causes guilt and shame, but Moses serves as an example that because of God's grace we are invited into God's presence. We have to simply take God at His Word and walk into His presence. A look how God has revealed Himself in His Word, a focus properly fixed on Christ, and a periodic self-reflection to make sure we are living a life of faith are practical steps to insure we are walking in God's blessing, life, and promise.
