Have you noticed how Trump has been consistently acknowledging God throughout his campaign and especially since the assassination attempt?
In his inauguration speech, he specifically said regarding the assassination attempt that he believes that "he was saved by God to save America".
Proverbs 3:6 - "In all thy ways acknowledge him, and he shall direct thy paths."
As we acknowledge and give thanks to God and seek His will (and genuinely repent and turn back to Him), He will bless us, and heal our nation.
2 Chronicles 7:14 - "If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and I will heal their land."
