God is so more and better than we are; so He is able to have us doing more and better than what we can now promise.
Plus, we do not know what will happen in the future.
So . . . though . . . there are times I feel I should make a commitment; but I say things like, "If the LORD wills", and I might say I won't make an actual promise but I "intend" to do something, plus I hope to do something better than what now I could think of promising.
And . . . usually . . . when I then do set out to do something . . . indeed I find that God has me doing it better than I was thinking and hoping . . . even, for example, when I first intended to write this post, I can find myself doing it better than I might have been thinking, at first
God can bless us to write or do what is more caring and better done, than what we might have been planning, at first.
And one of the best things surprising us can be the people and the loving which we could not have arranged or planned.
God does not want you to just make promised gestures to Him; He has loving and caring and sharing for you with others, as family in Jesus and doing what can help people to become adopted to become children of God. So, in case you make a promise, this could be a way of isolating yourself with your own mind and abilities . . . versus getting into doing things in sharing with God and one another as His family. So, I would not make promises that can limit you to yourself and isolate you with controlling your own self so you are alone. Instead, we need to get more with one another Jesus people as family and then discover what we do in unity with one another.
