Joining forces with God means that you first of all are on the winning side of every battle. God had it from the beginning that you would be blessed. Gen. 12:1-3 ( You are the spiritual seed of Abraham).That means to be strengthened, healthy, satisfied, not only with the blessings in your immediate family, but your church family, your nation, etc. Joining His forces brings about a good disposition amongst those that surround you. Because the Father and yourself settle things on the covenant He’s established. Then both of you work together, together, together, in bringing about its reality in your lives.
1 Corinthians 3:9 King James Version (KJV)
9 For we are labourers together with God: ye are God’s husbandry, ye are God’s building.
You & He, there is no greater team. 😉
