How can I know if I'm in Christ?

Believers can be assured of their standing in Christ by examining whether they have faith in Him as their Savior. As stated in John 3:36, 'He that believeth on the Son hath everlasting life.' This faith is given by God and is the evidence of one being chosen in Christ. It isn't about one's own works or decisions but rather the acknowledgment of Christ's redemptive work and the recognition of oneself as a sinner in need of grace. True faith produces assurance and demonstrates that one is indeed in Christ.
