How can we make God be with us? Jesus spoke about this: “You will love the Lord your God with all your heart and your neighbor as yourself”.
The apostle John expressed:
22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
23 And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
24 And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
1 John 3:22-24
The key is not any in-depth science or something we must figure out. The key is simple. Do you really believe in the Lord? So give yourself to Him, love Him with all your heart, that He be first in our lives, and this is followed by living a life that pleases God in every way.
But, I can’t say that I love God that way when I don’t love my neighbor. So, by loving one another we demonstrate that God really abides in us.
In conclusion, loving God and our neighbor, then the Spirit of God remains in us and bears witness to that.
