Hebrews 12:28,29 Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, for "our God is a consuming fire". (Deut 4:24)
Deut 4:31 For the Lord your God is a merciful God; He will not abandon or destroy you or forget the covenant with your forefathers, which He confirmed to them by oath.

During my time in college, I was in a class that taught "Situational Ethics". We were given a situation that attempted to explain that there are no absolutes and that we must make decisions according to the present circumstances. We were encouraged to find solutions to different sets of events that were 'fair' to all.
The word 'sin' was unacceptable and archaic. The idea that we will someday stand before a Holy God and pay the price for our sins was old-fashioned and a more 'modern' way of thinking was to be embraced. I found it very difficult to 'embrace' a way of thinking that denies the sovereign will of God.
The Lord Jesus has paid a very high price for an 'archaic way of thinking'. He gave up His Heaven for a time on earth with a people that insisted on rejecting Him despite many miracles and healings. He loves us just as He loved them. He
has paid the same price for us that He paid for them. He gives us the same choices that He gave them. He hasn't changed His ways or His free gift of salvation. He rejoiced over them the same as He rejoices over us when we confess our sins, repent and take advantage of His sacrifice.
He is the same yesterday, today and forever. He will not change. He is the same God that spoke the universe into
being. He is the same God that took the dust from the ground and made the first man. The covenant that He made with Adam is unchanged today. The Son of Man is coming to crush the head of the serpent and to set up His kingdom here on earth. The beauty of the Heaven that He has promised is beyond our comprehension.
We are guaranteed that He won't change His mind. We are promised that we will see Him face to face. We know that His Word is absolute. The love of God is, was and will always be. You can be sure of that.
