3 Things God cannot do

God cannot Lie

The Bible reminds us that His wirds are true, because God cannot lie

In hope of eternal life, which God, that cannot lie, promised before the world began; But hath in due times manifested his word through preaching, which is committed unto me according to the commandment of God our Saviour; - Titus 1:2

God cannot change

Unlike us, God is unwanting and constant: I am the Lord, I change not

For I am the Lord, I change not; therefore ye sons of Jacob are not consumed. - Malachi 3:6

God cannot allow sinners into heaven

Jesus said, Except a man be born again, he cannot see the kingdom of God. - John 3:3

This is a bad news for us, because

For all have sinned, and come short of the glory of God - Romans 3:26

To enter heaven, we need new life.
Because God lives us, He has provided the way for us to be born again and cleansed from sin:

And they said, Believe on the Lord Jesus Christ, and thou shalt be saved - Acts 16:31


Obedience is a key principal for any believer and it is not an optional choice but compulsory, which should never be a burden for regenerated person but should always be blessing in scantification.
