I agree, we should look at individuals through the heart. I personally look for the character (spirit) of that individual. It assists in connecting, it sets the stage for trust between us. In my opinion it is to recognize who that individual is spiritually!
In closing I see the bottom-line here is to know the depth of your faith in order to continue under God’s covering we need to recognize our body is the temple Yeshua occupies with the Holy Spirit.
We must remain in faith knowing God’s with us protecting our beings and homes as He states. It becomes important for us to realize God’s protection may come in different ways. He may send messengers with specific tasks which involve us, our families, and homes. Our faith must never be blind, but always unwavering. Be aware of your temple and who shares it with you. Remain in charge of completing the tasks our Father calls us to accomplish as His servants.
