The LORD assigns Canaan as an inheritance to Israel. The boundaries that the LORD further indicates do not correspond to those which He has named to Abraham (Gen 15:1818On that day the LORD made a covenant with Abram, saying,
“To your descendants I have given this land,
From the river of Egypt as far as the great river, the river Euphrates:
). The area He promised Abraham is much larger.
The border is already indicated here. The border separates what is of God from what is not of Him. It is necessary that we know what to conquer and what not to conquer. A border indicates an area, but at the same time it delimits to what is outside. If God indicates the borders of what we should conquer, we should not conquer the wrong pieces. Here we see that the wilderness side of the Jordan falls outside. We should not make things our property that God has not given us as inheritance.
For example, the borders of our spiritual land are indicated in the letter to the Colossians. There we see that we have died and been raised with Christ. We are called to seek “the things above” (Col 3:11Therefore if you have been raised up with Christ, keep seeking the things above, where Christ is, seated at the right hand of God.). We have part “in the inheritance of the saints in Light” (Col 1:12-1312giving thanks to the Father, who has qualified us to share in the inheritance of the saints in Light.13For He rescued us from the domain of darkness, and transferred us to the kingdom of His beloved Son,). It is about Christ in us, He is our life.
The border of the land is what belongs to Christ. We are warned of what lies outside, so that we do not allow ourselves to be captured by it: “See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ” (Col 2:88See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ.). Here we speak of philosophy and the traditions of men. That is beyond the borders. We should not get involved in this. Philosophy and tradition impair the fullness of God in Christ in Whom we are brought to fullness.
Canaan itself is called “the Beautiful [Land]” (Dan 8:99Out of one of them came forth a rather small horn which grew exceedingly great toward the south, toward the east, and toward the Beautiful [Land].). It borders on wildernesses and seas and is surrounded by unattractive landscapes. The inheritance given to the church in Christ is connected to the Father. This inheritance is in stark contrast to everything that the world contains and has to offer: “For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world” (1Jn 2:1616For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world.; cf. Acts 26:17-1817rescuing you from the [Jewish] people and from the Gentiles, to whom I am sending you,18to open their eyes so that they may turn from darkness to light and from the dominion of Satan to God, that they may receive forgiveness of sins and an inheritance among those who have been sanctified by faith in Me.’).
We must not go beyond what God has revealed to us. The borders within which we can enjoy everything God has given us are set by God’s Word. These borders are there, so that we may respect them, so that we may remain in the enjoyment of the blessing. Exceeding God’s borders means losing the blessing.
