Once you have trusted in Jesus Christ for your salvation you can not loose it.
Nothing can snatch you out of His hands or the Father’s hands and you are sealed with the Holy Spirit and it dwells in you forever.
Titus 2:13 looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus,
Once you have trusted in Jesus Christ for your salvation you can not loose it.
Nothing can snatch you out of His hands or the Father’s hands and you are sealed with the Holy Spirit and it dwells in you forever.
