12 Therefore, brethren, we are debtors—not to the flesh, to live according to the flesh. 13 For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live. 14 For as many as are led by the Spirit of God, these are sons of God. 15 For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.” 16 The Spirit Himself bears witness with our spirit that we are children of God, 17 and if children, then heirs—heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together. Romans 8:12-17.
It is important to understand that those who are led by the Spirit of God are the children of God. We cannot claim to believe in or follow Jesus Christ and continue in habitual sin. The death and resurrection of Jesus Christ does not give me license to continue in sin and continue to walk according to the flesh.
It is important to recognized that those who walk according to the flesh will die by the flesh. When we come to Christ we face a daily decision to follow Jesus Christ. There have been some who have begun with Jesus Christ, but they have chosen to walk away. We cannot have our salvation stolen from us, but if we abandon faith in Jesus Christ we abandon eternal life.
When we continue in the flesh, sin has in incredible way of hardening ones heart to the Lord. Dabble in the things of the flesh is a very dangerous thing because the more we indulge the more we become bound by the things of the flesh. The Lord has compassion on us and He knows our struggle but again this does not give us the right to continue to walk according to the flesh.
Through Jesus Christ we become the adopted sons and daughters of God. This is why when someone says that we are all children of God they are wrong because the only ones who are truly children of God are those who have placed their faith and trust in Jesus Christ. Let us draw near and develop deep intimacy with the Lord.
