We praise God for His faithfulness, His Grace, His Mercy, and His love that forgave our sins. But...we cannot pull the grace card everytime we want to sin or do things contrary to His Word. Yes God is just and faithful to forgive. Just meaning He is fair, faithful because He made a promise through His covenant with us through the blood of His dear Son Christ Jesus. But as Paul let us know in Romans 6:1 that God's forgiveness and goodness IS NOT AN EXCUSE TO SIN.
