It has been said if you can’t stand firm, then you won’t stand at all. We see this proven out in our spiritual lives. No one can claim they stand for Jesus if they won’t stand for Him under trials and difficulties. Standing firm means to stand without wavering. You can’t be a warrior for Jesus one day and live your life as if He wasn’t Lord the next.
In Ephesians 6:10-18, Paul tells us to always be prepared for the day of battle by putting on the full armor of God. If we do that, we will hold fast to Christ regardless of what the enemy sends our way (Ephesians 6:13). The easiest way to not lose our footing is to never take our eyes off Jesus, never stop delighting in His Word, and never stop reminding ourselves that our life is not our own (1 Corinthians 6:19-20; Galatians 2:19-20).
