How do you know this ??? Where is it found in the Bible ?
How do I know what is spiritual.
"But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him, neither can he know them, because they are Spiritually discerned" 1 Corinthians 2:14
Therefore you would have to know the difference between the spiritual grave and the physical grave.
The physical grave is what you can see
The spiritual grave, can not be seen, that's why it's spiritually discerned.
The grave in which Christ Jesus spoke about, is not the physical grave, But the spiritual grave.
When Christ was put in the tomb after his death, Christ defeated the captivity of the grave.
"But God will redeem my soul from the power of the grave: for he shall receive me"
Psalm 49:15
Where once in time pass, before Christ Jesus, people were held captive by the grave, That now by the death of Christ Jesus in the tomb, Christ Jesus defeated the power of the grave.
"O death, where is your sting?
O grave, where is your victory"
1 Corinthians 15:55.
The victory of the grave, Christ Jesus defeated at his resurrection from the grave.
That where once the grave held it's victory over us, that now Christ Jesus defeated the power of the grave that it had over us. That now when we die, the grave has no power to hold us, That we by pass the grave, to the victory of Christ Jesus.
The only thing the grave has, is our dead body corps that returns to dust. but our spirit by passes the grave to go to be with God.
