Exodus 23:20 “Behold, I send an angel before you to guard you on the way and to bring you to the place that I have prepared. Pay careful attention to him and obey his voice; do not rebel against him, for he will not pardon your transgression, for my name is in him.
Exodus 14:19 Then the angel of God who was going before the host of Israel moved and went behind them
Psalms 91:11 For he will command his angels concerning you to guard you in all your ways.
Isaiah 63:9 In all their affliction he was afflicted, and the angel of his presence saved them; in his love and in his pity he redeemed them; he lifted them up and carried them all the days of old.

The Book of the Covenant terminates, very appropriately, with a series of promises. God is “the rewarder of them that diligently seek him.” He chooses to “reward men after their works,” and to set before them “the recompense of the reward.” (Ellicott)
It is here promised that they should be guided and kept in their way through the wilderness to the land of promise, Behold, I send an angel before thee, mine angel. The precept joined with this promise is, that they be obedient to this angel whom God would send before them. (Henry)
The declaration of the rights conferred by Jehovah upon His people is closed by promises, through which, on the one hand, God insured to the nation the gifts and benefits involved in their rights, and, on the other hand, sought to promote that willingness and love which were indispensable to the fulfilment of the duties incumbent upon every individual in consequence of the rights conferred upon them. These promises secured to the people not only the protection and help of God during their journey through the desert, and in the conquest of Canaan, but also preservation and prosperity when they had taken possession of the land. (Keil)
THE REWARDS OF OBEDIENCE. God always places before men” the recompense of the reward.” He does not require of them that they should serve him for nought. The “Book of the Covenant” appropriately ends with a number of promises, which God undertakes to perform, if Israel keeps the terms of the covenant. (Unknown)
God’s promises for obedience and warnings for disobedience are consistent.
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed. But whoever does what is true comes to the light, so that it may be clearly seen that his works have been carried out in God.”
