Neither present (mhde paristanete). Present active imperative in prohibition of paristanw, late form of paristhmi, to place beside. Stop presenting your members or do not have the habit of doing so, "do not go on putting your members to sin as weapons of unrighteousness." Instruments (opla). Old word for tools of any kind for shop or war ( John 18:3 ; 2 Corinthians 6:7 ; 2 Corinthians 10:4 ; Romans 13:12 ). Possibly here figure of two armies arrayed against each other ( Galatians 5:16-24 ), and see opla dikaiosunh below. The two sets of opla clash. But present yourselves unto God (alla parasthsate eautou twi qewi). First aorist active imperative of paristhmi, same verb, but different tense, do it now and completely. Our "members" (melh) should be at the call of God "as alive from the dead."
