Romans 8: 5-12
5Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God. 9 You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ. 10 But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life[d]because of righteousness. 11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of[e] his Spirit who lives in you. 12 Therefore, brothers and sisters, we have an obligation—but it is not to the flesh, to live according to it. 13 For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live.
Paul's letter to the Romans identified some things that we should know and observe after we have received Christ into our life. It's important to know that there is a mental transition that must occur in every believer so that we are walking according to the Spirit. We have two mental states, (1) carnal and (2) spiritual, and it is up to us to choose which one we will seek and serve. Paul's letter should make our choice very easy; for carnality leads to sin and death and spiritual leads to life and peace. Roman 8:5 says that they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. If we are after the flesh, then our flesh and carnal thoughts take first place in our mind; our flesh is the leader and everything else follows behind it. If we are after the Spirit, then He [the Spirit] is our leader.
Our minds can only be in tune with the Spirit when we seek after and follow the Spirit. We put ourselves in position to reap spiritual things which is life and peace. Seek it and you will find it.
What is the first thing on your mind when you go to bed at night or wake up in the morning? What type of thoughts do you allow to consume your mind throughout the day? Do you let doubt, fear, anxiety, frustration have first place in your heart or do you set your affections on heavenly [spiritual] things such as peace, life, and joy? When was the last time your entire day was led by the Spirit and you did not waver between earthly concerns and spiritual promises? If it has ever happened, then pray and ask God to help you to stop wavering. When you are led by the Spirit, you will notice that your circumstances and situations will begin to look smaller. God will keep you in perfect peace when your mind is stayed on him (Isa 26: 3).
I believe when we think about what is on our mind, it gives presents the opportunity to make the necessary adjustments to our thoughts. Move out doubt, move in hope; move out fear, move in trust; move out anxiety, move in rest; move out sin, move in life. So now...what's on your mind?
