The first thing that comes to mind when we use the word give is financial gifts. While financially partnering with God and His local church is certainly one way to give, it is not the only way to give to God. God has gifted each and every member of His church with a way to serve Him. He has given each of us unique talents and passions which we are expected to offer back to Him in return.
When a believer looks at their checkbook or personal calendar, it should reflect how he or she gives back to God. This service we offer to God is not done under compulsion, or under a sense of obligation to gain merit or favor in His eyes. Instead we should give of ourselves in a manner of gratitude for all that God has done for us.
Romans 12:4-8 NIV
For just as each of us has one body with many members, and these members do not all have the same function,  so in Christ we, though many, form one body, and each member belongs to all the others.  We have different gifts, according to the grace given to each of us. If your gift is prophesying, then prophesy in accordance with your faith;  if it is serving, then serve; if it is teaching, then teach;  if it is to encourage, then give encouragement; if it is giving, then give generously; if it is to lead, do it diligently; if it is to show mercy, do it cheerfully.
It’s always been God’s intention to make us like His Son, Jesus (Romans 8:29). When we look at Jesus’ life, there’s no denying that He was a servant. Jesus’ entire life was centered on serving God—by teaching, healing, and proclaiming the Kingdom (Matthew 4:23). He came not “to be served but to serve” (Matthew 20:28). Then, on the night of His arrest, Jesus washed the disciples’ feet, leaving them with a final teaching to serve one another: “I have set you an example that you should do as I have done for you” (see John 13:12–17). So, if Jesus is all about serving, and God wants to make us like Him, then it’s pretty obvious that we should be all about serving as well.
Genuine service cannot be separated from love. We can go through the motions of serving God, but if our hearts are not in it we’re missing the point. First Corinthians 13 makes it clear that, unless our service is rooted in love, it’s meaningless. Serving God out of a sense of obligation or duty, apart from love for God, is not what He desires. Rather, serving God should be our natural, love-filled response to Him who loved us first (see 1 John 4:9–11).
The Bible offers several motivations for our service. We want to serve God because “we are receiving a kingdom that cannot be shaken” (Hebrews 12:28), because our service supplies “the needs of the Lord’s people” (2 Corinthians 9:12), because our service proves our faith and causes others to praise God (2 Corinthians 9:13), and because God sees and rewards our labor of love (Hebrews 6:10). Each of these is a good reason to serve God.
We can give away only what we’ve first received. The reason we can love and serve God is that He first loved and served us through Jesus Christ. The more we are aware of and experience God’s love in our own lives, the more prone we are to respond in love by serving Him. If you want to want to serve God, the key is to get to know Him! Ask the Holy Spirit to reveal more of God to you (John 16:13). When we truly know God, who is love (1 John 4:8), our natural response is a desire to love and serve Him in return.
