Hi Rick, we all come here to discuss our opinions about these things... what we should respect is what we find to be sound from the Scripture.
I believe New years resolutions is not only a waist of time but its a sin too. Its true.
So a resolution is setting a goal, planning ahead and it appears you believe that is a waste of time and actually a sin, because we cannot determine what is actually going to happen? Well you're right we do not know for sure what even tomorrow holds...
James 4:14 whereas you do not know what will happen tomorrow. For what is your life? It is even a vapor that appears for a little time and then vanishes away.
So there James shows what the person that really does not consider God in their thinking/planning is like. It's like the parable of the rich man in Luke 12 and God called him a fool for storing up so much wealth. But can and should a person that is striving to obey and serve God ever make plans? Well James goes on to say we should humble ourselves before God, and in planning strive to do so according to God's will.
James 4:15 Instead you ought to say, "If the Lord wills, we shall live and do this or that."
So it's about our attitude towards God, whether we are humble to understand that God rules in our lives and planning. We see that Paul thought this way when making his plans.
1Cor 16:7 For I do not wish to see you now on the way; but I hope to stay a while with you, if the Lord permits.
Acts 18:21 but took leave of them, saying, "I must by all means keep this coming feast in Jerusalem; but I will return again to you, God willing...
Heb 6:3 And this we will do if God permits.
So I don't see it as sin for the God fearing person to make resolutions or plan ahead, because we need to make plans to travel just like Paul did and a resolution is just resolving/planning to do something. But it certainly is wise when we consider and plan to do so with God's will in mind.
Pro 21:5 The plans of the diligent lead surely to abundance, but everyone who is hasty comes only to poverty.
Luke 14:28 For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it?
Pro 6:6 Go to the ant, O sluggard; consider her ways, and be wise.
v. 7 Without having any chief, officer, or ruler,
v. 8 she prepares her bread in summer and gathers her food in harvest.
Pro 15:22 Without counsel plans fail, but with many advisers they succeed.
I hope you find this helpful, as I am just trying to understand what the Scripture say on this or any matter.
mercy, peace and love
