Eph 1:13 (CSB), “In him you also were sealed with the promised Holy Spirit when you heard the word of truth, the gospel of your salvation, and when you believed.”
Years ago, I came to Christ in a not too dramatic way. Simply put, I heard the gospel, I responded to the gospel, and I was changed by the gospel…slowly. What I mean is that it took time for me to grow and live in Christ, but He was patient with me! He brought godly people and even some circumstances to help me grow. But most of all, God brought me to the Word.
We are all called to the gospel to walk in Christ as an example to others (see Mt 5:16), but we all know that this is hard! Life, work, distractions, sin, flesh, etc. pull us away, but let me encourage you: don’t give up. As what Paul wrote, that you were called to Him, you were sealed in Him and you are already redeemed in Him. The Spirit is with you whenever you go, so trust Him to help you to walk in Him. Signed, sealed, and delivered, you are His! He who has called you is faithful to complete you until the Day of Christ.
Let that sink in as you struggle through whatever you are going through.
