Following are a number of back-translation of 1John 3:24:

Yatzachi Zapotec: “If we are doing what he commands, we are constantly with God, and God is constantly with us. And we know that he is constantly with us because he has given us his Spirit.”

Eastern Highland Otomi: “Whoever does what he says, lives with God, and God also resides in his heart. And we know that we live with God because he gave us his good Spirit.”

Tzotzil: Because if we obey his commands, we are in his presence. God is in our hearts. Because is in our hearts the Holy Spirit that God has given us, therefore we know that God is in our hearts.”
