If .05 is the rejection level, we would reject the null hypothesis if the probability of the test statistic, given that the null hypothesis is true, was .07.

The rejection level (also known as the significance level, denoted by alpha) represents the maximum probability of rejecting the null hypothesis when it is actually true. In other words, if the rejection level is .05, it means that we are willing to accept a 5% chance of making a Type I error (incorrectly rejecting a true null hypothesis). Therefore, if the probability of the test statistic, given that the null hypothesis is true, was .07, it would not meet the rejection level criteria and we would not reject the null hypothesis.
