“Do our actions justify us to get to heaven?”

Galations 3:2-3
"..Are you so foolish? After beginning with the Spirit, are you now trying to attain your goal by human effort?"

Galations 3:10
"... All who rely on observing the law are under a curse, for it is written: ‘Cursed is everyone who does not continue to do everything written in the Book of the Law. v 25 Now that faith has come, we are no longer under the supervision of the law." (Because faith is a higher standard than the law. See Mathew chapter 5 The Beattitudes)

Galations 5:4
"... You who are trying to be justified by law have been alienated from Christ; you have fallen away from grace. v 6 The only thing that counts is faith expressing itself through love. v 13 You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love."

Galations 6:3
"...If anyone thinks he is something when he is nothing, he deceives himself. Each one should test his own actions. Then he can take pride in himself without comparing himself to somebody else, for each one should carry his own load."
