“Let us hold fast the confession of our hope without wavering, for He who promised is faithful.”
Jesus Christ is God’s ultimate plan for mankind’s salvation. Part of the encouragement to “hold fast” given here comes from that perspective (Hebrews 3:14). Christ is the fulfillment of God’s will for mankind, so we should resist the pressures of anything which tries to take us away from Him. We are called to embrace the confidence we have in Christ, and His salvation, and act accordingly.
God Bless You
