Am I in Christ Jesus or not?

2 Corinthians 13:5
Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the test?

Romans 6:23
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

Romans 8:1-2
Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit of life set me free from the law of sin and death.

Romans 8:38-39
For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.

I can be "in" ministry, church, good relationships, and also be "into" living according to God's "law" but if I am not "in Christ Jesus" I am deceived to think that any of the things that I'm "into" will save me in the day of God's judgement and wrath. I'm hopelessly "in my sin" if I'm not "in Christ Jesus". As a Christian, if I'm not seeking His presence more than His principles I begin to live by the law and the law's purpose is to show me my sin and need of forgiveness and salvation. Living by the law doesn't save only being "in Christ Jesus" saves.

Romans 10:9-11
That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. As the Scripture says, "Anyone who trusts in Him will never be put to shame."
