Red stands for God's Love.
God sent his only son, the Lord Jesus to this world.
He was born as a baby and did nothing wrong.
Because He was God.
But one day, wicked man nailed him on the cross and he bled and died.
"Without the shedding of blood, there is no forgiveness" Hebrews 9:22b
The Lord Jesus took the punishment of death that you and I deserved for our sins.
All our sins was put on the sinless Son Of God.
"Christ Died for our sins according to the scriptures, that he was buried, that he was raised on the thrid day according to the scriptures..." 1 Corinthians 15:3&4
After 3 Days God raised the Lord Jesus from the dead!
He is now in Heaven with his Father God.
