“What shall we say then? Are we to continue in sin that grace may abound? By no means! How can we who died to sin still live in it?” (Romans 6:1-2 ESV)
Grace gives no excuses to sin. If you give excuses for sinning after you’ve been given grace you do not completely understand grace. You don’t understand the grossness of sin. You don’t understand the glory of Christ.
Sin might look cute in kids. Sin might be expected in teens. Sin might be hidden by crafty adults. But that gives not excuse to sin. That only abuses grace.
