You were dead, but God has made you alive with Christ and has set you free from all that bound you.
If you understand the reality of what happened to you in Christ, you will resist the temptation to live as though you need to add something to His work.
Unless you are actively guarding your heart, you are at risk of being taken captive by persuasive lies. How do you guard your heart?
If you want to be unshakable in a shaky world, you must let Christ form the foundation, determine the structure, and shape the attitude of your life.
Living out the Christian life is only possible if you receive Christ Jesus the Lord.
