Colossians 3

Affection is the feeling or emotion, the quality, condition, and the state of the body, mind, and heart. Whatever our affections are, we need to set them on the right things.
Colossians 3 talks of a new life or putting on a new self and exhorts Christians to set their affections on things above.
Apostle Paul exhorts us as he did the Colossians to be heavenly minded after the example of Christ, that we may be prepared to appear with him in glory. He exhorts us in Vs 5-7, to change our minds and lives, and not continue in our former state.
From our conversion, we shared not only Christ’s death, but His resurrection, then get to participate in His heavenly life, the heaven where He is, and where He sits at God’s right hand. That means we must let our whole thought be set on heavenly, and not on earthly things. Your life will always remain hidden in Christ, for at Christ’s second coming it will be revealed because Christ is our life, which means His manifestation involves ours.
Put to death that and deprive your life or body of that thing the power to destroy your spiritual strength. Put to death any sensual appetite, deprive it of the nourishment by which it lives, thrives, and is active. However, the body may suffer from excessive sensual indulgences, the appetite increases with the indulgence.
We must not set our affections on inordinate affection—unnatural and degrading passion, or bestial lusts according to Romans 1:26, 27. Selfish and ungodly affections create a system of idolatry producing all kinds of impurity.
The list of ungodly and earthly affections includes both the acts and motive. If the affection is yours then you can set it on the right things, godly things, and heavenly affections rather than allow it to meander to the wrong things. According to Psalm 145:16, God will open His hands and satisfy only the pure and Godly desires of His people.
Paul has described what is true of us positionally, directing our attention to the practical influence of the truth of God’s word over our mindsets.
According to Romans 6:11, we are to reckon ourselves to be dead to sin, but alive to God in Christ Jesus our Lord. Meaning to accept what God says about us as true and to live in the light of it. It means we must believe what God says in Romans 6:6. This demands a definite act of faith, which results in a fixed attitude toward “our old self.” We will see our old self where God sees him, on the Cross, put to death with Christ.
There is a distinction between natural and spiritual or gracious affections. The affections of the world are strong, but they are not spiritual, they are not born of the Holy Spirit nor are they awakened by the New Testament, and they are not the affections for God as sovereign God. When we incline our hearts to seek the Lord and desire only Him according to 1 Kings 8:58, we begin to set our hearts on things above and not on the earth as stated in Vs 2. Set you your affections, tune it until it aligns with God’s desire and affections.
Shalom
