Anyway, I think, to answer my first question, that Scripture warns against anything disrupting a healthy relationship with God.

²⁵ Now great crowds accompanied him, and he turned and said to them,

²⁶ “If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple.

²⁷ Whoever does not bear his own cross and come after me cannot be my disciple.
Luke 14:25-27

If we love anything more than God, even our own families, we hurt our relationship with Him. The rich young ruler went away sad because he loved his money more than he wanted to follow God.

So, can we collect things? I think so. Like I said, I collect pocket knives. And I created a really cool list for all the Case Select knives produced from 1998 until now . . . did I already say that?

But when collecting, or money, or family issues, or ebay, or T.V., or friendships, or food (like Chocolate Peanut Butter Umpqua) or anything at all – gets in the way of following Jesus Christ – we need to let it go.

¹ Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us,

² looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.
Hebrews 12:1-2
