God most assuredly commands that which is impossible.
How about the 10 commandments? We are told that it is impossible to keep the law, in the NT. The Law exists not as a means of salvation but as a mirror and standard to see sin by. Thus the law exists as something impossible for any man except Christ.
And again, Christ said "be perfect as your Father in heaven is perfect". Is that possible? Of course not.
Thus, I derive two truths from these facts:
1) Command does not imply ability
1A) in some cases, it instead serves to show our inability, in fact.
2) God has, and does, command what is impossible.
I see one of two things of why a man does not keep the commandments.
1. He is still bound by sin, and sin is his master.
2. If he is freed from sin, he refuses to obey them.
Concerning no. 1, I think it's pretty much self-explanatory.
Concerning no. 2, does the Bible say we CANNOT do ALL things through Christ? If you can't keep the commandments, then I can assure you, it's not because Jesus isn't there to help you. It's not the absence of ability which prevents one from obeying, it's unwillingness.
Which of the 10 commandments are you having problems with? If you do not keep them, how will you inherit eternal life if you don't do what they say?
Luke 10
25 And, behold, a certain lawyer stood up, and tempted him, saying, Master,
what shall I do to inherit eternal life?
26 He said unto him, What is written in the law? how readest thou?
27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
28 And he said unto him,
Thou hast answered right: this do, and thou shalt live.
Again, I ask,
which of the 10 commandments are you having problems with? Do you have murder brewing within you? Do you lust after your neighbor's wife? Are you wanting to steal something? Can you not love the Lord with all your heart? Can you not love your neighbor? Perhaps, you have problems with lying.
Humble yourself before the Lord, and He will give you grace to help with these things. Beseech the Lord to help you. Repent and seek the Lord. Don't excuse yourself and break these commandments. It has nothing to do with inability, but rather, it's unwillingness.
And yes, you can be perfect as Jesus told us. Read that verse in context, and not by itself. If you can't love your enemies, then no, you cannot be perfect.
Get off your monergism duff and show the Lord He is your Master. Show Him you love Him by keeping His commandments. Stop the excuses and obey. Why is this so hard for Christians? I don't want to hear your theological excuses. They won't help you in the day of judgement, for it is your works, not your beliefs, that will be judged.
Sorry if this seems a little rough, but sometimes it takes a knock in the head for us to see things, and get us going. It's not 'means', it is OBEDIENCE! If you are a servant of Christ, you have absolutely no say in obeying the Master; it is required of you. Do not rebel against the Master, or He will remedy the situation.
He has given you everything you need to obey Him (the Word, the Spirit, the ability); you have no excuse to not obey Him. The choice is freely up to you to obey Him, and that is the ONLY thing which prevents you from obeying His commandments.
In His love,
