The three questions of Paul

Hebrews 5:8 Though he were a Son, yet learned he obedience by the things which he suffered;
Philippians 2:8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.

Through sufferings he learned and became obedient unto death, even the death of the cross.

Galatians 3:1 YLT O thoughtless Galatians, who did bewitch you, not to obey the truth -- before whose eyes Jesus Christ was described before among you crucified?

It had been described to them the sufferings of Jesus and his learning obedience all the way unto death on the cross.

So Paul asked them in the next verse; Was it not by hearing of faith, Jesus learning through sufferings and becoming even obedient unto the death of the cross, crucified verse 1, by which you received the Spirit or did you receive the Spirit because of your works of the law?

Which brings the next question from Paul. Galatians YLT so thoughtless are ye! having begun in the Spirit, now in the flesh do ye end?

Begun in the Spirit. Having received the Spirit because Jesus learned through suffering and became obedient unto death even the death of the Cross, the faith of Christ; Now you want to go out on your own rather than like I said of myself: Gal 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
