This is all that most trust in

Take heed of being deluded by common presumptions. Most men have some thoughts in general about what their state is, and what it will be in the issue; but they make no diligent search into this matter, because a number of common presumptions do immediately insinuate themselves into their minds for their relief; and they are such as all whose force and efficacy to this end lies in this, that they differ from others, and are better than they; as that they are Christians, that they are in the right way of religion, that they are partakers of the outward privileges of the Gospel, hearing the word, and participating in the sacraments; that they have light and convictions, so as that they abstain from sin, and perform duties so as others do not; and the like. All those with whom it is not so, who are behind them in these things, they judge to be in an ill state and condition, whence they entertain good hopes concerning themselves; and this is all that most trust in. (John Owen. The Glory of Christ p229)

May God the Holy Spirit use these words of Owen to shake us from the condition he describes.
