He says to us through His word...
“I will not leave you as orphans; I will come to you. Yet a little while and the world will see me no more, but you will see me. Because I live, you also will live. In that day you will know that I am in my Father, and you in me, and I in you. Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him.” (Jn 14:21 ESV)
"Therefore, my beloved, flee from idolatry. I speak as to sensible people; judge for yourselves what I say. The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread. Consider the people of Israel:d are not those who eat the sacrifices participants in the altar?" (1 Cor 10:14-18 ESV)
