How many people live in past experiences thinking those experiences are adequate for today's challenges? Individuals fail the Lord because they assume that what they received from Him in the past is adequate to overcome present or future challenges.
A relationship with Christ and the Holy Spirit involves a daily relationship with daily prayer and daily bible reading. For example, a wedding doesn't create a relationship between a man and a woman. A relationship between a husband and wife is created by daily commitment and communication after the wedding.
The same is true in having a relationship with Christ and the Holy Spirit. The salvation experience doesn't create a relationship with God. Salvation puts us in right standing in order to start a relationship with God. The relationship is developed by working through the daily events that come our way in seeking after God and His plan for our lives.
To live in past experiences is to live in deficiency. Past experiences were for past challenges and events that needed overcoming. What about today's challenges?
Yes God could supply us with an experience that would span our lifetime and conquer any challenge that comes our way. He could give us a "one-time" experience that could handle anything and we would never need another experience again.
However where is the relationship? Where is the communication and the commitment to draw closer to God? Living in past experiences limits progression in the Lord and a closeness that He desires from us.
God is not about giving us experiences that we can just bask in for the rest of our lives. God is a about giving us a relationship that we can develop in and draw closer to Him. He wants us to know Him and not just experience Him through blessings or "feel-good" situations.
Christians have an obligation to grow in the Lord. Paul said in Philippians 3:13,14: "Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before. I press toward the mark for the prize of the high calling of God in Christ Jesus." Also read Philippians 3:10.
It's good to have experiences in the Lord and to enjoy those moments in life. It's also good to remember those experiences and cherish them for the rest of your life. However it's not good to live in those experiences as if they were meant to exist forever.
Christians need to meet the challenges of today. To do that requires a daily relationship with Christ and the Holy Spirit that supplies the power and strength to overcome those challenges. Such a lifestyle will not be accomplished if people assume that what they have experienced in the past is adequate for today.
