What is important for our salvation is the power of God's word, not our thoughts. The Israelites won the battle at Rephidim as Moses held up his arms. This was a prophecy that God’s people would win the spiritual battle against Satan as Jesus was lifted up on the cross.
And also The Israelites were killed by venomous snakes bite in the wilderness, and when they came to live by God's word, they forgot the invisible word of God and made snakes in bronze to worship.
Likewise, it is an act to be cursed to forget the Passover covenant, which contains the promise of the blood of Christ who saved us, and to build and worship the cross. From the Old Testament to the present, God has forbidden Idolatry. We do not build crosses according to the teachings of Christ AhnSahnghong and Heavenly Mother. We only remember Christ's sacrifice and love and do as God says.
