We are in the world of self-deceit that we are too focused on ourselves to see the eternal truth. When truth speaks, there is not burdens but rather "The truth shall make you free"; that is, free from the woes, the yokes, the burdens. To avoid causing others to stumble is itself strong incentive to walk by the Spirit. Biblically, Christians are no longer "in the flesh": "You are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Flesh follows the rules while Spirit follows the conviction of the Holy Spirit.
But if anyone does not have the Spirit of Christ, he does not belong to Him" (Rom 8:9). "If we live in the Spirit, let us also walk in the Spirit." Galatians 5:25. The Holy Spirit dwells in me with all the power and gifts of God, necessary to enable me to walk the noble, spiritual, Son-like life with God. Being thankful releases me from fear and worry. The presence of worry could mean a believer doesn't understand who God is in order to trust Him. In my life, I have learned to trust every situation to God's sovereign control. "God is able to make all grace abound to you, so that in all things at all times, having all that you need, you will abound in every good work." (2 Corinthians 9:8). Reading 2 Corinthians 12:9 says "God said 'My grace is sufficient for you, for my power is made perfect in weakness.' Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me." First Peter 5:7 "Cast all your anxiety on him because he cares for you".
The main thing to understand and remember is that Jesus is OUR SHEPHERD that He will supply all our needs (Phil. 4:19) and that He knows everything about our lives (Ps. 139:3), cares about us (1 Pet. 5:7), has the power for every difficulty (Ps. 62:11), is perfecting us to be like Christ (Phil. 1:6), and that nothing escapes Him (Ps. 147:5), that will lead us to be stable, not anxious living.
