In Isaiah, chapter fifty-five, verse eight, “For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.” God’s thoughts and ways are not those of the natural person. But human minds and hearts can be renewed and transformed by seeking Him, as in Romans twelve, verses one through two; then our thoughts and ways will begin to conform to His. Our greatest desire should be to so live in conformity to the likeness of our Lord that everything we do pleases the God we serve. We can do this by abiding in His Word and responding to the leading of the Holy Spirit.
Paul describes in Romans eight, verses five through fourteen, the two classes of people: those who live according to the sinful nature and those who live according to the Spirit. This nature includes being occupied with the fleshly desires, thoughts, emotions, and physical gratification. There is also sexual immorality, adultery, hatred, selfish ambition, outbursts of anger, drug addiction, obscenity, and so forth.
To live after the Spirit is to seek the Holy Spirit’s direction and enablement, and to focus one’s attention, thoughts, energy, and values on the things of God. It is to live consciously at all times in the presence of God, trusting Him to give us the help and grace we need to accomplish His will in and through us.
Our thoughts are not the thoughts of God because initially we were born in sin. However, as a baby, we are innocent because we are born into the world. Then, as we grow, hopefully, learning as God ordained, the proper things in life as we develop and mature. As we grow older and are aware of the things in life, we will choose to live godly before God the Creator.
