Galatians 3:10-14.  Remember that Paul is dealing with the challenge of a false teaching in Galatians. The “troublers” from Jerusalem have convinced the Gentile Galatians that they need to add obedience to the Mosaic law (as defined by Jewish tradition) to their faith in Christ in order to have the blessing of Abraham.

But Paul’s point is that the blessing of Abraham comes by faith in Christ’s atonement on the cross of Calvary. So one of the consequences of the cross is that the Gentiles are now included in God’s promises to Abraham when they put their faith in Christ.
That blessing includes forgiveness of sins and adoption as sons of God.
Another consequence of the cross is that the Holy Spirit is now available to everyone (Jew and Gentile). Fellowship with the Holy spirit brings power into our lives (Spiritual Gifts) and transforms us so that we manifest the Fruit of the Spirit (sanctified lives).

The Galatians were being tricked into rejecting Christ and going back to the old choice (self reliance) which only leads to sin and destruction. What about you? Are you trusting in the blood of Christ for your salvation, or are you trying to be good enough for God to save you?
LORD, we hereby renounce the old way of self-reliance, and cling to the cross of Christ. We accept the redemption bought by his blood. We accept your forgiveness and adoption into your family. We accept transformation by your Holy Spirit. Amen
