Link Deut 11:8 & Eph 6:10 on strength.
How does Deuteronomy 11:8 connect with Ephesians 6:10 about spiritual strength?

Strength Rooted in Obedience: Deuteronomy 11:8

“You shall therefore keep every commandment I am giving you today so that you may have the strength to enter and possess the land that you are crossing the Jordan to occupy.”

• Strength is explicitly linked to keeping God’s commands.

• The promised land represents God’s tangible inheritance; obedience equips Israel to take hold of it.

• Obedience is not merely rules-keeping—it is active trust that God’s way brings power for victory (cf. Joshua 1:7-9).


Strength Restated in Christ: Ephesians 6:10

“Finally, be strong in the Lord and in His mighty power.”

• The command now centers on union with Christ: “in the Lord.”

• God still supplies the power; believers receive it by faith and obedience (John 15:5; 2 Timothy 2:1).

• The context shifts from physical conquest to spiritual warfare (Ephesians 6:11-17).


A Single Thread: God as the Source of Power

1. Same Author, same principle

• Deuteronomy: covenant obedience → strength for conquest.

• Ephesians: covenant union with Christ → strength for warfare.

2. Same goal

• Deuteronomy: possess Canaan, the earthly inheritance.

• Ephesians: stand firm, advance the gospel, anticipate the heavenly inheritance (1 Peter 1:4).

3. Same means

• God supplies power, but His people must act—“keep every commandment” / “put on the full armor.”

• Strength grows where dependence and obedience meet (Psalm 18:1-2; Philippians 4:13).


Practical Applications: Walking in Strength Today

• Guard daily obedience to Scripture; it is still the pipeline of divine power.

• Draw strength consciously “in the Lord”—pray, abide, and lean on His promises before acting.

• Face spiritual battles with the same confidence Israel had before the Jordan: God’s strength is enough when we heed His Word.
