There are many things that affect the atmosphere, first of all you must make sure all things are right in your heart and keep them as pleasing to God as possible.
James 3: 16-18 says in the Amplified…For wherever there is jealousy (envy) and contention (rivalry and selfish ambition), there will also be confusion (unrest, disharmony, rebellion) and all sorts of evil and vile practices. But the wisdom from above is first of all pure (undefiled); then it is peace-loving, courteous (considerate, gentle). [It is willing to] yield to reason, full of compassion and good fruits; it is wholehearted and straightforward, impartial and unfeigned (free from doubts, wavering, and insincerity). And the harvest of righteousness (of conformity to God’s will in thought and deed) is [the fruit of the seed] sown in peace by those who work for and make peace [in themselves and in others, that peace which means concord, agreement, and harmony between individuals, with undisturbedness, in a peaceful mind free from fears and agitating passions and moral conflicts].
When you keep jealousy, envy, strife and those types of things out of your life, the presence of God will remain in your life. But if you allow those things in your life and allow them to remain, the Bible says you will also allow confusion and every evil work to come in.
I don’t know about you but I want an atmosphere where God is pleased to dwell, not to visit occasionally but to dwell, to make His abode, therefore I do my very best to keep an atmosphere that is conducive to His presence. I want His presence, more than I want anything else. I want His presence to dwell in my life, in my home, in my vehicle, in our ministry, I want His presence. For me, just like Moses said ‘if His presence isn’t there, I don’t want to be there either.’ That is my stand and that is why I protect the atmospheres around me.
