Before entering the land, the people must deal with their fear and self-righteousness, which had previously led to their rebellion against God (Num 14). To combat their fear, Moses reminds them of God's almighty power (3). To prevent groundless pride, they must understand that it is not because of their righteousness that they will receive this land. God was judging these wicked nations and keeping his promise to Abraham, Isaac, and Jacob.
To remain humble and depend on God's grace, they must never forget how stiff-necked they were. Moses reminds them of the Golden Calf incident (16) and their rebellion at Kadesh Barnea (23). The covenant God established with them was broken almost immediately. It could not be a basis for righteousness, only guilt. But Moses interceded for them in fasting prayer on the basis of God's grace and promise (26-27). Remembering the past makes clear God's grace of redemption, God's mediator, God's promise and not their righteousness, that brought about his blessing. In the same way, we are redeemed by Jesus' death and resurrection. Jesus is a superior mediator than Moses (Heb 8:6; 9:15). Jesus is the fulfilment of God's promise. As we dwell on these truths, we, too, will avoid the pitfalls of fear and self-righteousness.
Application: Father, thank you for Jesus, my Savior and Lord. Help me remember your grace so I may not become ruled by fear or by self-righteousness.
One Word: Righteous only by Jesus' blood
