When you find yourself behaving like the elder son in the Prodigal story,
Judging who God can save or forgive?
Who can come to Him and who shouldn't?
Who should be honour and celebrated and who shouldn’t
Who God should accept and who He shouldn't?
- check your heart.
The elder son felt he was righteous and deserved to be celebrated because he stayed home. There was nothing wrong with that, it was the state of his heart that was not right.
Think of this, all that the Father has already belongs to His sons and daughters and we all are saved by grace. Nothing else.
