Leviticus 1:3 If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD.
I love this verse. I know I love so many of them you are beginning to wonder but I do love the Word of God. The worshipper was to offer his offering in a certain way. One of the ways that offering was to be given was “of his own voluntary will.”
Do you see that? They were to come with their offering because they wanted to do so. They were to go to their flock and offer to God what was in their heart. God will tell them what offering was acceptable. They were to offer it because after understanding what God wanted they were to do His will from the heart.
God lays out what He wants. You decide to do what you ought to do because you want to please God. Your offering will be accepted because it is what He wants and it comes from your heart.
