"For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live." - Romans 8:13
I'm having a hard time wrapping my head around this one. Particularly if we're saved by grace and not of works (Ephesians 2:8-9) how can Paul say that if we live after the flesh that we'll die or if we mortify the deeds of the body that we'll live?
What kind of dying and living is Paul talking about in Romans 8:13?
Works alone saves nobody, faith alone saves nobody, it is the combination of the two that leads to salvation.
James 2:18-26
18But someone will say, You have faith and I have works. Show me your faith apart from your works, and
I will show you my faith by my works. 19You believe that God is one; you do well. Even the demons believeand shudder!
20Do you want to be shown, you foolish person, that
faith apart from works is useless? 21Was not Abraham our father justified by works when he offered up his son Isaac on the altar?
22You see that
faith was active along with his works, and faith was completed by his works;
23and the Scripture was fulfilled that says, Abraham believed God, and it was counted to him as righteousnessand he was called a friend of God.
24You see that a person is justified by works and not by faith alone. 25And in the same way was not also Rahab the prostitute justified by works when she received the messengers and sent them out by another way?
26For as the body apart from the spirit is dead, so also
faith apart from works is dead.
Jesus said that we must love God to enter heaven and how does Jesus expect us to show this love?
If you love me, you will keep my commandments. (John 14:5)
Paul is simply saying we cannot live according to the desires of our body and expect to be saved. If you live for the body then you are living for this world and you are serving the ruler of this world.
I will no longer talk much with you,
for the ruler of this world is coming. He has no claim on me, (John 14:30)
But, if we live according to the spirit which is not of this world then we are living for God.
What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us. (1 Corinthians 2:12)
So the death mentioned is hell, and the life is heaven.
