Input: The Power of What We Allow Into Our Lives

The quality and nature of what we permit to enter our lives—whether through our senses, relationships, or media consumption—fundamentally shapes our character, decisions, and ultimate destiny.

The Principle of Input Determines Output

Input determines the output. We are basically what we allow into our lives – be it food and addictive substances into our bodies, information and images into our minds, or hurts we permit to take root in our emotions. Do I take seriously the Bible's counsel to "Guard your heart [inner-most being] more than any treasure for it is the source of all life" and out of it comes all sorts of evil (Prov 4:23; Mt 15:11,18-19). Establish self-imposed boundaries using uncompromising values coupled with discipline, self-control and accountability, then continually monitor your behaviour. "The entrance (unfolding) of your Word gives light" (Ps 119:130). The Bible also counsels us, "Whatever is good, pure and wholesome, think about these things" (Phil 4:8).

It is very important to have the right input into our lives, be it through the eye gate or ear gate, because what goes in determines to a large degree what ultimately comes forth. Satan is always looking for ways to gain the advantage over us; from seemingly innocent encounters, footholds gained soon become habits and, unless addressed, strongholds become established (Eph 4:27; 1 Pet 5:8). We reinforce the input by revisiting memories, replaying images and fantasizing. The input, because it shapes our attitudes, values and beliefs will be outworked in some form in our lifestyle – be it to our shame or honour. We determine our own destiny. It is the principle of sowing and reaping.

We need to keep a close watch on the material going into our minds and the confession we speak. Many TV programs and magazines are loaded with pornographic images besides other unhealthy and unhelpful matter that do not advance spiritual growth. Our five senses of seeing, hearing, tasting, feeling and smelling provide input into our body and mind.

Spiritual Input and Nourishment

As we can't give out from an empty heart, it is essential to receive spiritual nourishment so we can give out to those around us, who need a touch from the Lord. We are to be channels through which His life flows to hurting humanity.

Biblical Examples of Sacred Input

Throughout Scripture, we see the importance of what we bring before God and what we allow to enter His presence. The wise men brought gold, frankincense, and myrrh—each representing profound aspects of Christ's nature (Mt 2:11). These were not random gifts but carefully chosen offerings of worship and recognition. In the Old Testament, the tabernacle and temple were filled with specific symbols and practices that represented God's holiness and the people's devotion. Incense represented prayer rising before God (Ps 141:2; Rev 5:8), while sacrifice demonstrated surrender and gratitude.

True worship involves bringing our best—our firstfruits, our purest praise, our undivided heart—before the Lord. When we approach God with worthy input, He honors our devotion and transforms our lives. The quality of our worship, prayer, and service reflects the quality of our spiritual input and preparation.

Reflection and Application:

• What inputs—media, relationships, conversations—do I need to limit or eliminate from my life?
• Am I actively feeding my spirit with God's Word, prayer, and wholesome fellowship?
• What boundaries do I need to establish to guard my heart and mind effectively?
• How can I ensure my spiritual input consistently exceeds my output?
