Jesus teaches the parable of the sower in Matthew 13:3-23. In this parable, soil quality represents heart condition. If the good seed (gospel /Kingdom message) falls on good ground (an honest, humble heart), it will bear much fruit (a Christ-like character). “…the fruit of the Spirit is love, joy, peace, long-suffering, kindness, goodness, faithfulness, meekness, self-control…” (Galatians 5:22-23 ASV).
God may allow, not cause, the plowing up of the soil (heart) by allowing difficult experiences to humble a person. This prepares that one to receive the gospel with the goal of bearing spiritual fruit. “…get rid of all moral filth and…evil…humbly accept the word planted in you, which can save you.” (James 1:21 NIV). In addition to God’s loving efforts on our behalf, we are responsible for actively maintaining pure thoughts and refusing to dwell on impure thoughts. It benefits us to avoid tempting sinful environments. “Keep thy heart with all diligence; for out of it are the issues of life.” (Proverbs 4:23 KJV). Philippians 2:12 (ASV) states “… work out your own salvation with fear and trembling.”
We should study the holy scriptures daily, applying the lessons to all areas of our lives. “…blessed are they that hear the word of God, and keep it.” (Luke 11:28 ASV). See also 2 Timothy 3:16.
We may freely serve God, our brethren, and fellowmen. “…God loves a cheerful giver.” (2 Corinthians 9:7 KJV). The heavenly Father expects us to lovingly serve our brethren, even those that seem to show us less warmth. “…let us do good unto all men, especially unto…the household of faith.” (Galatians 6:10 KJV).
Developing perfect love is essential to entering the kingdom. By meeting with other Christians, we assist and encourage one another in spiritual goals (see Hebrews 10:25). If we are willing, God will work in us, giving us desire, strength and ability to do His good pleasure (Philippians 2:13).
We must pray continually (1 Thessalonians 5:17). A constant trusting connection to Jehovah is vital to spiritual health and peace (see Isaiah 26:3).
Although we try desperately to do good God’s will, sometimes we will fail, but “…a righteous man falls seven times, and rises up again…” (Proverbs 24:16)
If possible, for our part, we should live peacefully with all (see Romans 12:18). “Follow peace with all men, and holiness, without which no man shall see the Lord.” (Hebrews 12:14 KJV). And remember Jesus instructs us in Matthew 6:15 to forgive others just as God forgives us.
This is how we can be fruitful.
