When I think of an action and a reaction, I immediately think of Galations 6:7-8 (NKJV), where Paul states:
“Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap. For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life.”
If we engage [sow] in the immoral vices of this world, i.e., “the flesh” (cf. 1 Corinthians 6:9-10; Galations 5:19-21; Ephesians 5:3-5; 1 Timothy 1:9-10), we will not inherit the blessings of eternity (1 Corinthians 6:10; Galations 5:21; Ephesians 5:5). But, if we choose to follow [sow to ourselves] the teachings of the Bible that the Holy Spirit has provided for us, i.e., “the Spirit,” we will reap or inherit those eternal blessings that God has promised all of those who love Him (2 Timothy 4:7-8). Note the action of sowing and the reaction of reaping in this principle.
To go along with Galations 6:7-8, Paul tells us in 2 Corinthians 9:6 (NKJV) regarding our giving:
“But this I say: He who sows sparingly will also reap sparingly, and he who sows bountifully will also reap bountifully.”
The same principle of sowing and reaping (action and reaction) holds true in our giving. If we sow sparingly, we will reap sparingly. If we sow bountifully, we will reap bountifully (cf. 2 Corinthians 8).
God’s principle of sowing and reaping (action and reaction) is simple. It’s putting the principle into practice that is difficult for many folks, including those in the Lord’s church.
