But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness and self-control.
Galatians 5:22 (NKJV)
Faithfulness is the seventh attribute of the fruit of the Spirit.
Pistis, the Greek word for faithfulness, means "enduring, holding fast, without wavering." There is a significant difference between knowing God is faithful and experiencing God's faithfulness. When we say God is faithful, we mean that He will do what is right and good in His eyes for us. In other words, God's purposes in our lives are consistent and persistent.
It is precisely because we do not have all of the answers that we jump to incorrect conclusions and make poor decisions. However, trusting in God's faithfulness provides the rest He promised. God knows how to navigate you through all of life's twists and turns and get you to where He wants you to be. It's like Jesus guiding his disciples through the storm to the other side. Instead of abandoning them, our Lord got into the boat, and they immediately arrived at the shore (John 6:21).
Just as God is faithful to us, we must remain faithful to God.
In Hebrew 11, we see a list of Old Testament faithful men and women who trusted God because they walked with Him. Similarly, as you walk with the Spirit, He will strengthen your capacity for faith and faithfulness. You cannot be faithful without faith, nor can you have faith without being faithful. Staying rooted and grounded in Christ provides an ideal platform for growing your faith. As a result, faith is a rest rather than a work because you are receiving from God something greater than your ability to produce.
Faith in God results in faithfulness to God.
The Apostle James aptly pointed out: "faith without [faithful] works is dead" (James 2:26). Faith spurs you to follow the Holy Spirit's leading and use the gifts He has bestowed upon you to serve God for the good of your church and community, and you will bear fruit that pleases and glorifies God.
