We grieve the HolySpirit when we operate contrary to Him. He is the Lord in us. We must learn to let Him use our body for His purpose. Rom 12:1<p>We are sealed by the HolySpirit so that -> we are marked as His property -> we are eternally preserved and secure in Him<p>The day of redemption is the day of our Lord`s return Luk 21:27,28.
