We can tell what God’s plan is by reading His Word, which reveals both His overarching purpose for humanity and His specific will for our lives. God's plan is always good, sovereign, and unshakable, even when it’s not fully clear to us (Jeremiah 29:11; Job 42:2). His will includes salvation, sanctification, joy, prayer, and gratitude (1 Timothy 2:3-4; 1 Thessalonians 4:3; 5:16-18). While many people seek specific answers to know God’s plan, much of God’s plan is already revealed in Scripture, inviting us to live faithfully, follow Jesus, and bring Him glory (Romans 12:2). No matter what we do, if we seek to glorify Him, we live within His plan (1 Corinthians 10:31). As we grow in relationship with God through prayer, obedience, walking in the Spirit rather than in the flesh, and in community, He unfolds His plan step by step (James 4:8).
God has given us plenty of His plan for us to follow. God’s plan is discernible through the Bible by God’s Spirit. For example, the New Testament contains various passages with commands to obey, so by reading them, we have plenty of opportunities to follow His will and plan.
Here is one example: "Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you" (1 Thessalonians 5:16-18). These three assignments, to rejoice, pray, and give thanks always, may offer enough instructions to follow for a lifetime!
However, most people want specific answers to life circumstances. Again, day-to-day instructions can be found in the Bible. Scripture provides guidance on how God calls us to live, specifically explaining how to honor and glorify Him in all we do (1 Corinthians 10:31). Also, by following Jesus, seeking to emulate Him, we find God's plan for our lives. When we offer ourselves to God and avoid the patterns of this world, we will be able to understand God's will (see 1 Peter 4:2).
He also communicates with us through circumstances, our relationships with those who strive to walk closely with Jesus, and other ways that are unique to each of us. Discerning God's plan is a spiritual muscle that must be exercised. He wants us to know Him, and know His will for our lives. The apostle James tells us to "Draw near to God, and he will draw near to you" (James 4:8).
