If it is really true that spilling Jesus blood on the cross has taken away people's sin past, present , future.Then why did Jesus not say that and give no further teachings ? Why did he tells us the kingdom of God is within us ? Why did he tell us we have to look at the beam in our eye that is within us ? Why did he tell us we have to be as little children to enter the kingdom who have a beginners mind ? Why did he tell us we have to put on the wedding garment to enter the wedding feast ? and so many more teachings ?
He provided
the way to receive eternal life, if one chooses Him now, and until His 2nd coming.
Past - In the OT they were saved by grace and faith believing in the Savior to come.
Present - If one has accepted the Savior, they have been saved and the kingdom (to come) is within them and will receive eternal life at His 2nd coming. We need Him now to help us through our earthly struggles with sin.
the beam - we are to look at our own faults and not judge others.
children - Matthew 18 -
6 But if anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea.
We are to teach children about the Lord and in no way impede their learning of Him.
Wedding garment - The king provided the wedding robes free of charge. Those present were invited randomly while traveling on the highways, and probably did not have the appropriate attire for the wedding, nor money to buy it. Both the invitation and the garment were gifts from the king. The only requirement needed to attend the feast was to accept both presents. (we are invited to accept Jesus and receive the gift of salvation)
and so many more teachings - His teachings are how to come to Him and receive eternal life through Him.
God Bless.
