What does 'alive from the dead' mean in Romans 6:13?

Les teaches that 'alive from the dead' refers to believers being raised from the deadness in the old Adam and now being alive unto God. He explains that this is why Paul says to yield yourselves unto God as those who are alive from the dead, because that is what we are. He then connects this to yielding your members as instruments of righteousness unto God. In the following verses, Les focuses on Romans 6:14-15, where sin—singular, old Adam—shall not have dominion. He defines dominion as ruling like a king, and says Paul admonishes us not to let old Adam have dominion over us. Les notes the seemingly anticlimactic reason: don't let old Adam have dominion because you are not under law but under grace. He points out that this is the opposite of what one might expect. He explains that we have full freedom, not under any demands of a set of rules and regulations.
