“Honor the Lord with your wealth and with the firstfruits of all your produce” (Proverbs 3:5). God gives us everything we have and he can be trusted to give us everything we need. To show that we trust Him, we give consistently.
“For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you by his poverty might become rich” (2 Corinthians 8:9).
Our response to God's generosity is to give sacrificially.
“Through the church the manifold wisdom of God might now be made known” (Ephesians 3:10). The church is God’s plan to reconcile the world to Himself through Christ. We give to advance the gospel through the church.
