God can’t lie
“a faith and knowledge resting on the hope of eternal life, which God, who does not lie, promised before the beginning of time,”Titus 1:2

God can’t change
“I the LORD do not change. Malachi 3:6
and
God can’t let you into heaven, UNLESS you are born again.
” 3In reply Jesus declared, “I tell you the truth, no one can see the kingdom of God unless he is born again.[a]”

4″How can a man be born when he is old?” Nicodemus asked. “Surely he cannot enter a second time into his mother’s womb to be born!”

5Jesus answered, “I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit.” John 3: 3-5

Have a great day!
