Galatians 4:8 Formerly, when you did not know God, you were enslaved to those that by nature are not gods. But now that you have come to know God, or rather to be known by God, how can you turn back again to the weak and worthless elementary principles of the world, whose slaves you want to be once more? You observe days and months and seasons and years! I am afraid I may have labored over you in vain.
1 Thessalonians 3:5 For this reason, when I could bear it no longer, I sent to learn about your faith, for fear that somehow the tempter had tempted you and our labor would be in vain.
Romans 1:28 And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done.
1 Corinthians 1:21 For since, in the wisdom of God, the world did not know God through wisdom,
Ephesians 4:18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart.
1 Chronicles 28:9 “And you, Solomon my son, know the God of your father and serve him with a whole heart and with a willing mind, for the LORD searches all hearts and understands every plan and thought. If you seek him, he will be found by you, but if you forsake him, he will cast you off forever.
Legalism caters to and recognizes our flesh by putting the focus on what we achieve for God, not on what Jesus did for us. We can have a living, free, relationship with God as a loving Father based on what Jesus did for us and who we are in Him. Or we can try to please God by our best efforts of keeping the rules, living in bondage as slaves, not sons. Living that way makes the whole gospel in vain. Such is the battle we all face. We lean more toward what we can do to make ourselves right before God rather than what He has done through Christ, thereby resting, relying on, and trusting in this alone. It is when we recognize, take captive, and discard these thoughts of self-reliance we will truly be able to honor and glorify Jesus Christ through faith in Him alone. If there was an equation, to sum up, this type of thinking it would be; My works + the work of Christ = eternal life. This way of thinking literally says Christ’s sacrifice was not enough. Anything added to Christ’s sacrifice for the forgiveness of sin = nothing, zero, failure. In Christ alone, there is forgiveness, salvation, redemption, and eternal life. Don’t be tempted or allow your mind to be tricked into thinking you can in any way add any benefit for your soul other than through Jesus Christ.
