Moses and the Isrealites conquered two kings: Sihon, king of the Amorites and Og, king of Bashan.
Joshua led the Israelites to conquer 31 kings their cities, people and everything included (Joshua 12)
Notice that although God had already told Moses and Joshua repeatedly that He had already given them (spiritually) the promised land; a land flowing with milk and honey, the Israelites still had to do their part:
a) believe what the LORD had said and
b) Go to war, fight and contend for their promises to manifest in the physical realm.
As a believer, our God has already blessed us with all we need in the spiritual realm (Ephesians 1:3)
All praise to God, the Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly realms because we are united with Christ.
Additionally, He has given us everything pertaining to life and godliness (2 Peter 1:3)
And has supplied all our needs according to His abundant riches in glory in Christ Jesus (Philippians 4:19).
The solution to the issue of not walking in the Spirit, lack, poverty, sickness, etc is to appropriate the finished work of Jesus’s death and resurrection by exercising our authority in the Name of Jesus (Philippians 2:9)
For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name; studying, meditating, and confessing the WORD, (Joshua 1:8), put on the whole armor of God (Ephesians 6:10-18), Praise and Worship, Prayer and stand on the WORD. All of God’s promises are true, they will surely come to pass if you persevere.
2 Corinthians 1:20 NLT For all of God’s promises have been fulfilled in Christ with a resounding “Yes!” And through Christ, our “Amen” (which means “Yes”) ascends to God for his glory.
Grace and peace be multiplied to you.
