# For what the law was unable to do because it was weak through the flesh, God did

"For the law did not have the power to stop us from sinning, because the power of sin within us was too strong. But God did stop us from sinning"

# through the flesh

"because of people's sinful nature"

# He ... sent his own Son in the likeness of sinful flesh ... an offering for sin ... he condemned sin

The Son of God forever satisfied God's holy anger against our sin by giving his own body and human life as the eternal sacrifice for sin.

# Son

This refers to Jesus, the Son of God. It is best to translate “Son” with the same word that your language uses to refer to a human son.

# in the likeness of sinful flesh

"who looked like a sinful human being"

# to be an offering for sin

"so that he could die as a sacrifice for our sins"

# he condemned sin in the flesh

"in Christ's flesh God condemned sin" or "by Christ's death God broke the power of the sin"
