“Therefore, since we have so great a cloud of witnesses surrounding us, let us also lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us, fixing our eyes on Jesus, the author and perfecter of faith…’”
Hebrews 12:1-2a NASB

The key here is not so much about what you are to lay aside but instead what you are to focus on. Because the power comes from what you are focusing on: Jesus. You will then have the power to lay aside what is distracting you and overwhelming you. I love what David tells us in in Psalm 62, “My soul, wait in silence for God only, for my hope is from Him. He only is my rock and my salvation, my stronghold; I shall not be shaken. On God my salvation and my glory rest; the rock of my strength, my refuge is in God. Trust in Him at all times, O people; Pour out your heart before Him; God is a refuge for us. Psalm 62;5-8 NASB”
