"I assure you: Everyone who commits sin is a slave of sin. A slave does not remain in the household forever, but a son does remain forever. Therefore, if the Son sets you free, you really will be free." - Jesus, in John 8:34-36
A son has a place in the household, an appointment given by his father. No decent earthly father fails to prepare an inheritance for his sons, and since this is so with earthly fathers, even more so it is with my heavenly Father, who is perfect and just. Therefore, hold fast, the promise will come at an opportune time.
Every opportunity that presents itself along the way must be weighed against what is promised, so that the son should not find himself in futile activity. And sometimes, it's best to hear from the Father Himself, since He gives the promise. And in Jesus Christ, all of God's promises are "Yes!", and mine to agree with an "Amen".
