Our own evil desires.
Sometimes when a man fell in a ditch and deep miry clay, tends to point fingers at others, forgetting that anything that drags us down to positions which we lose the touch of God is ourselves! Nobody is to be blamed but us. Temptations is what the enemy entices us with, because the devil no longer has power, in these end times he studies a human being thoroughly then set a temptation that suits their evil desires. Know that as long as we're in this world evil thoughts and desires will always be present! Temptations are the only warfare we are fighting against, warfare is not all about shouting and praying hard but it is all about casting away and cutting off all evil thoughts which gives birth to evil desires. Even though a temptation may look good and sweet, it's end is gravel and graveyard! The only purpose of temptation is to drag us away from who God is in our lives. For temptation always enters in a house unoccupied! Occupy your salvation with God's presence.
