If the Church isn't doing their duty, taking care of the closest needy, or the sheep of that flock, before helping others abroad; then what you give to those needy close by, and what you give as special gifts, counts as service to the Most High: of course keeping in mind, not to do these things to receive praise from other people, but rather to Glorify the goodness of the Most High.
This lack of wisdom in stewardship, is a big problem in todays churches, as the blind often leads the blind. In many cases wisdom in stewardship is completely lost, and those who should be good stewards of their flocks, have in some ways, become like the hording cat lady: who without taking proper care of the cats she has; then goes out to gather more cats, where in neglect, they all together perish faster. You must first take care of what you have, before expending resources to gather more. The great commission wasn't just about spreading the word of redemption, it was also about spreading the wisdom of all scripture, teaching about taking care of each other in love, and being good stewards of the flock. People forget the church isn't a building, it's the people of the congregation.
There is a reason in scriptures, those who went out abroad in the great commission, or missionary work, were commanded to take nothing with them: as that would show little faith in who they serve, while also taking away from the local flock. Also in scriptures, those who when out on the great commission, where mature enough in there faith, to teach wisdom and faith: by knowing the Most High who they serve, can bring water from the rock, mana from the Heavens, coins from a fishes mouth, oil and flour from empty jars, also multiplying fishes and loves. We again need this kind of faith, the faith of a mustered seed. Everyone in these times puts their faith and understanding in man, not understanding what it means to put faith in the Most High. Ironically we're on a permaculture site, and for those who have faith know, permaculture teaches the Most High knows better then man, as we learn to go back to the systems in nature He created, many for agriculture even written in scriptures, for those who have knowledge in the word. Thats why people are also eating Ezekiel bread again, because it's very healthy.
It was always meant to take proper care of the flocks as first priority, an unspoken common sence, while scriptures gives many clear examples of this. A good shepherd has strong healthy flocks. A good shepherd leaves his flock on good pasture, whith adequate shelter, water and protection from preditors: before he leaves the 99 sheep, to find the one sheep thats lost. Sadly this wisdom has been lost, and good stewardship is no longer understood amongst the leadership in these times. It's become more about gathering sheep to sheer their wool, to make more money, to gather more sheep, to also sheer their wool, excetra. All the while, those sheep are left scattered and neglected, perishing in preditor infested over grazed pasture, only gatherd for the shearing.
Now remember regardless what men teach, tithe as it was written, is 10% of your best first fruits, in due season, as outlined in scriptures: anything else is considered a special gift, in service to the Most High. Your described intentions could also be considered loving your neighbor, unless your going beyond your neighbors, and doing what the church stewardship has neglected, in taking care of the body. You can direct your special gifts to the purpose of your choosing, and if the leadership isn't being good stewards as it was written: your service in undertaking that responsibility of stewardship, will also be as a special gift in service to the Glory of the Most High.
So much wisdom has been lost, because most people don't know whats in their Bible; however, if you write it all on your heart, searching out that wisdom like your greatest treasure: knowing the Messiah is also the Word which always was spoken; then wisdom starts to reveal itself, when people rely not on their own understanding, and look to understanding as it was written, even in the hard sayings which perplex mankinds own understanding.
If some of that seems discouraging, let me share the good news: everything will be restored, the path will again be made straight, every vally lifted up, and it was all written.
Blessings to you, I hope that helps!
