God’s ten commandments have always been there to guide people.
God has used so many ways to reconcile humans to Himself.
The difference between good and evil was always ever laid on people’s conscience,- even now.
Prophets prophesied about the coming of Jesus.
And even when he came, as God the Son and Man to teach the same same word, based on the 10 Commandments, to reveal who God the Father is, and how to follow His ways and how to go to Him, many still didn’t and don’t believe.
God knows different generations and He knows the power and magnitude of evil that would end up destroying souls at future generations.
Sacraments that we have today, 7 sacraments in Catholic church, are the graces given to us, at our times so they can help us to overcome the powers of evil at our time.
They will always be there,because God never changes His plan of Saving us, Human.
What’s different?
Maybe the bible alone was enough weapon at some past generation, but now the bible and the sacraments are necessary; and Prayers, as means to talk to Him.
Prayers like the Rosary, are necessary too. I love when St. Dominic foretold, “Mary will give to my order, a weapon, “The Rosary” and to St. Agnes he said, “Mary will give a scapula”. With this weapons, she will help us overcome the evils in our time”
Different prayers at different times, like Devine Mercy and many more.
My thought,
God is always standing besides us, He knows what we need when we need it and He is always helping us to remain His children; giving us different graces to help us go to Him after our Journey.
If you read different apparition messages of the past or now, Jesus would tell the seer that Satan does not like when people spread certain devotions, or this devotion will destroy Satan’s ways, or it will convert souls(Example, Sacred Heart Devotion).
He was always there to help at the times those saints went to the wilderness, He used their meditations and prayers and afforded them all the graces that helped them go to heaven.
So, when Satan changes His game, We have to worry NOT, For as long as we are on His light, He will fight for us, Just as He did for the Saints.
