Luke 23:40 - Wesley's Explanatory Notes

The other rebuked him — What a surprising degree was here of repentance, faith, and other graces! And what abundance of good works, in his public confession of his sin, reproof of his fellow criminal, his honourable testimony to Christ, and profession of faith in him, while he was in so disgraceful circumstances as were stumbling even to his disciples! This shows the power of Divine grace. But it encourages none to put off their repentance to the last hour; since, as far as appears, this was the first time this criminal had an opportunity of knowing any thing of Christ, and his conversion was designed to put a peculiar glory on our Saviour in his lowest state, while his enemies derided him, and his own disciples either denied or forsook him.
