The Lord has sealed us with the promise of the Spirit in our hearts. We have the guarantee of our salvation and that He who began a good work in us will be faithful to complete it. Careful though, we can still grieve the Holy Spirit when we trifle with sin, or allow the devil to have his way with us. With acts of commission and omission, doing things we shouldn’t and not doing things we should. Thankfully, and in spite of us, the promise the Lord has made will not be broken.
