Because God is all-powerful and perfect, the thought of attempting to please Him can be scary. Pleasing God, however, is not difficult because He gives us everything we need to please Him (2 Peter 1:3). Pleasing God involves obeying His commandments, living righteously, and genuinely worshiping Him. God is also pleased with a contrite heart and humility because this attitude allows us to see who we are in light of who He is. This allows us to do what is most important in pleasing God: trusting in Him. After salvation, living in the Spirit enables us to live in ways that please God (Romans 8:5–8). Believers should seek to know, follow, and reflect God's character, knowing that God equips us to live pleasing lives through His grace and the Holy Spirit.
Throughout Scripture there are many verses which outline the sort of life Christians are to live. In short, they are to be characterized by love of God and love of others, all based on truth. Those commands are not meant to be a burden. "For this is the love of God, that we keep his commandments. And his commandments are not burdensome" (1 John 5:3). His commandments are not burdensome because He gives us everything we need for life and godliness (2 Peter 1:3), He has perfected us by Jesus' sacrifice (Hebrews 10:14), and He has given us the Holy Spirit, who is like living water flowing out of us (John 7:38). The point is that once we are in Christ, pleasing God is inevitable, because God will make it happen. We are saved by His grace, through faith, and it is all a gift, including the good works that we will eventually come to learn to do (Ephesians 2:8–10). Believers should never worry, thinking that they will not be pleasing to God. As we seek Him, and love Him, He will produce fruit in us that pleases God (John 15:4–5).
