What we once were no longer has any claim on us. We are not obliged to obey the desires of our old earthly nature
The lower nature does not automatically fade away when a person comes to Christ. The need to put to death the evil practices of the body is ongoing. Note as well that the way to crucify the old self is to obey the promptings of the Spirit. When we walk in fellowship with the indwelling Spirit, the desires of the lower nature are not met. For all practical purposes they are put to death. It is only when we break fellowship with the Spirit that our sinful nature is able successfully to reassert its fraudulent claim on our lives. The key to freedom from what we were is constant reliance on the active presence of the Spirit
While God is the Father of all in the sense of creation, and specifically the Father of Israel in a corporate sense (Deut 32:6; Isa 63:16; Jer 31:9), the only way for a person to become a child of God is through faith in Jesus Christ (John 1:12–13). The corollary is that unless people are continually being led (indicated by the Greek present tense) by the Spirit, they are not members of God’s family. The NIVSB note on 8:14 says that “being led by God’s Spirit is the hallmark of this relationship.” Beware of the temptation to adjust this requirement to the level of common practice.
In adoption all previous relationships are severed. The new father exercises authority over the new son, and the new son enters into the privileges and responsibilities of the natural son. “Abba,” the Aramaic word for “father,” was used primarily within the family circle and in prayer (cf. Mark 14:36; Gal 4:6). Montgomery’s translation (“My Father, my dear Father!”) underscores the intimate nature of the expression, which is so clearly the opposite of fear
What our own spirit assures us to be true is strengthened by the powerful inward testimony of God’s Spirit. In much the same way that the hymn writer knew that Jesus lives (“He lives within my heart”), we rest assured that we are actually members of God’s family because the same Spirit witnesses to our spirit that it is so.
What appears to be a condition on this promised inheritance (“if indeed”) is actually a simple statement of fact. Sharing the sufferings of Christ leads to sharing his glory. Obviously we do not share the redemptive suffering of Christ, but we do share the consequences in terms of opposition from the world he came to save (cf. Phil 3:10; 1 Pet 4:13). As members of the same family we share in the trials of life as well as the benefits
