We are found in Christ having His sinless righteousness and on that basis we may freely enter the Father's presence. Our sins were judged on the cross and in that great day our works will be judged but our salvation is indeed still found in what Jesus did and not our own works.
We go to with with God when we die:
2Co 5:8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
