[Ali Imran]

Does not make sense

Allow me to explain. Our prophet صلي الله عليه وسلم taught us these in that Hadith.

1. We are created with a propensity to sin. 
2. Our mistakes and transgression are a part of a learning process.
3. We also have the conscious to realise we have sinned.
4. Our Lord is most merciful and often forgiving.
5. We should never lose hope of our Lord's forgiveness.

Ask me more.
