The sword of the spirit is application of God's Word everyday. When you are reading God's Word you pray for the Holy Spirit to draw you closer, reveal truth, and guidance over what you read today. This is how God's character is revealed to you. You start to understand His love, wisdom, how to identify sin, avoid temptation, understand truth, and reliance on God.
When you are done with your alone time with God, then you should be ready to face the world. You have what you need to practice being more like Jesus, overcome temptation, apply discernment and wisdom in action or words, and be a powerful agent for the Holy Spirit. You want to be in the Bible everyday to renew your mind, but also to become bold. You will never feel like you know enough, but you can stand by your convictions when you understand how to be a witness.
You will face challenges today. You will face them with God or pushing Him out of the way. You will face it, but you can do so with confidence that you faced it well with God. The Holy Spirit has given you spiritual gifts, use them to be bold in serving God and facing challenges without sinning. It takes work to live in peace. You need God's Word to understand how to apply the full armor of God to face the true battle which is invisible.
