This is part 19 of "The After Party," our series at Fusion Christian Church on the book of Acts. Follow along as we explore what happened to the church after Jesus ascended to heaven. In this sermon, Pastor Matt uses the Apostle Paul's teaching in Acts 13 to explain how we should be like King David.

A heart after God trusts.

David learned from his youth to trust in the Lord through his trials. Trusting God in battles against wild animals gave him the confidence to challenge Goliath, knowing that God would be with him. If we are to have a heart after God like David did, it starts with trusting in him.

A heart after God worships.

When David brought the Ark of the Covenant into Jerusalem, he danced with all his might. David was fully committed to praising God in that moment and declared that he would become even more undignified for the sake of the Lord. This ought to be the attitude of all Christians. With a heart after God, we are dedicated to praising God.

A heart after God repents.

Perhaps most importantly, David exemplified a lifestyle of repentance. Repentance is not a one-time event, but a continual choice for every person. Since we will not be able to stop sinning before death, we must keep repenting each time we do stumble. David did this throughout his life, and it is why he was called a man after God's heart.

What God promises he will fulfull.

For those who put their faith in Jesus, God has promised to finish the work of salvation within them. Like repentance, salvation is not a single event, but an ongoing process completed at the final resurrection. God gives the Holy Spirit to believers as a guarantee that he will complete our salvation. In the meantime, there are a few ways we can and should serve God's purpose.

Work hard.

Christians should not be lazy. Our actions represent Christ to the world and we ought to reflect him well.

Work intentionally.

When we work, we work with purpose. Christians are called to make the most of every opportunity and do all our work as though it is directly for God.

Live with joy, prayer, and gratitude.

Christians who maintain these three things will shine like stars in a dark world. Joy, even in sorrow, is a great testament to the hope Christians have in Jesus. Prayer keeps our thoughts continually on God. Gratitude keeps us humble and positive by helping us to hold God's blessings in mind. How can you cultivate these three in your life?
