15 Now where it says,
“Today, if you hear God’s voice,
don’t harden your hearts, as you did in the Bitter Quarrel,”
16 who were the people who, after they heard, quarreled so bitterly? All those whom Moshe brought out of Egypt. 17 And with whom was God disgusted for forty years? Those who sinned — yes, they fell dead in the Wilderness! 18 And to whom was it that he swore that they would not enter his rest? Those who were disobedient. 19 So we see that they were unable to enter because of lack of trust.
It is only by trusting in God will we ever move forward into our rest with Him.
