Genesis 28:12-15
12 He had a dream in which he saw a stairway resting on the earth, with its top reaching to heaven, and the angels of God were ascending and descending on it. 13 There above it stood the Lord, and he said: “I am the Lord, the God of your father Abraham and the God of Isaac. I will give you and your descendants the land on which you are lying. 14 Your descendants will be like the dust of the earth, and you will spread out to the west and to the east, to the north and to the south. All peoples on earth will be blessed through you and your offspring. 15 I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised you.”
Matthew 28:19-20
19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
