For you know the grace of our Lord Jesus Christ, that though He was rich, yet for your sakes He became poor, that you through His poverty might become rich. (2Corinthians 8:9)
that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus. (Ephesians 2:7)
And God is able to make all grace about toward you, that you, always having all sufficiency in all things, may have an abundance for every good work. (2Corinthians 9:8)
For by grace you have been saved, through faith, and that not of yourselves; it is the gift of God, for we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. (Ephesians 2:8, 10)
While there is a sense across Scripture in both the Old and New Testaments that if you didn't give in order to get, then you didn't give, you mocked God, there is also the sense in Scripture of giving because of Your identity in Christ Jesus, where we give because in Christ Jesus, by faith and not by sight, we are as rich as we are completely free of sin.
Sowing and reaping is only good stewardship. Reaping is a stewardship responsibility, and not how your needs are to be met. Your needs are met by grace through faith, according to His riches in glory by Christ Jesus. If you're not in actively engaged reaping mode, where you are automatically expecting more than a hundredfold from the Lord of the harvest, then you are the wicked servant who buries their talent and will have their place in the Lake of Fire, according to Lord Jesus.
It is never ok to not be actively stimulating your faith for infinitely more, otherwise you are leaving some area of needs unmet in some area of the Creation. But being wealthy is who you are in Christ Jesus, not how your needs are met. It's a righteousness in Christ issue. By faith, 1Timothy 6:17 says how you are to be behaving: trust in the living God, Who gives us richly all things to enjoy; for our enjoyment. When you trust in Him, then you can do what verses 18 through 21 say to do to lay hold on genuine life.
