Look at this – even when he knew his mother’s plan was wrong, his concern wasn’t that they shouldn’t do it but that they might get found out and reap the consequences! ‘We might appear to be tricking him’? Well yes, that’s because you would be tricking him! There’s no ‘appear’ about it!
Amazing that God uses us despite the deceitful, manipulative, impure motives of our hearts, and accomplishes his purposes anyway!
